Choosing between Hermès Bleu Encre and Bleu Nuit for a Birkin comes down to a fundamental preference in undertone and visual utility: Bleu Nuit is a strict, ultra-dark navy with charcoal-black undertones that serves as an impeccable, softer alternative to true black, while Bleu Encre (Ink Blue) is a saturated, jewel-toned indigo laced with deep purple undertones that shifts dynamically under direct light. If your wardrobe demands an understated, near-black neutral that recedes into the background, Bleu Nuit is the correct choice; if you prefer a complex, ink-like blue that reveals its violet depth when caught by the sun, Bleu Encre will better serve your collection.

Why This Matters: The Nuance of Hermès Blues

To the uninitiated, a dark blue handbag is simply navy. To the Hermès collector, navy is a vast spectrum of historical dyes, chemical formulations, and light-reflective properties. Hermès has mastered the blue spectrum like no other artisanal house, creating legendary shades ranging from the bright, electric Bleu Hydra to the muted, grey-toned Bleu Orage. Within the realm of deep, dark blues, Bleu Nuit and Bleu Encre occupy a highly contested space.

Selecting the wrong dark blue can disrupt the curation of a capsule wardrobe. A bag that looks like a midnight neutral indoors might suddenly flash a bright purple-blue in the daylight, clashing with cool-toned greys or warm earth tones. Conversely, a bag bought to add a subtle pop of color might end up looking indistinguishable from black in evening settings. Understanding how these pigments behave on different leather grains, under varying lighting conditions, and alongside specific hardware finishes is the key to making an informed, high-value acquisition on the secondary market.

The Chromatic Profiles: Bleu Encre vs. Bleu Nuit

Bleu Nuit: The Midnight Chameleon

Introduced in the mid-2010s, Bleu Nuit is the French house’s definitive take on midnight blue. It is formulated with a heavy concentration of black and cold grey pigments, stripping away any trace of warmth or green. In low-light environments—such as a dimly lit restaurant or under overcast skies—Bleu Nuit is frequently mistaken for Noir (black). Only under direct sunlight or crisp LED lighting does its true navy character reveal itself. It is a quiet, highly disciplined color that offers all the styling versatility of black but with a softer, more intellectual edge.

Bleu Encre: The Fountain Pen Indigo

Released for the Autumn/Winter 2018 collection, Bleu Encre translates literally to "Ink Blue." It is inspired by the rich, concentrated fluids of vintage fountain pens. Unlike Bleu Nuit, which leans toward the black-grey spectrum, Bleu Encre is heavily saturated with violet and royal blue undertones. It possesses an inherent warmth and vibrancy that prevents it from ever being mistaken for black, even in shadow. It is a jewel tone at heart—moody, artistic, and highly reactive to light. Under warm incandescent bulbs, the purple undertones dominate; under natural daylight, it presents as a striking, deep indigo.

Leather Behavior: How the Grain Alters the Color

The leather you choose dictates how these complex dyes are absorbed and reflected. Hermès pigments do not behave uniformly across different hides; a color can look remarkably flat on one leather and incredibly deep on another.

Togo and Clemence: Depth and Texture

On grained, natural leathers like Togo and Clemence, both colors exhibit excellent depth. The natural variations in the grain create tiny shadows that play with the light. For Bleu Nuit, Togo leather softens the darkness, preventing it from looking too harsh or uniform. For Bleu Encre, Togo leather emphasizes the purple undertones within the veins of the hide, giving the bag a multi-dimensional, velvety appearance. Clemence, being slightly heavier and slouchier, gives both blues a more casual, matte finish.

Epsom: Structure and Saturation

Epsom is a pressed, rigid leather that does not absorb dye in the same manner as natural grains. Instead, the pigment sits on the embossed surface, resulting in a highly saturated, uniform color presentation. Bleu Nuit in Epsom loses some of its mysterious, near-black quality and appears as a crisp, definitive dark navy. Bleu Encre in Epsom becomes incredibly vibrant; the rigid structure and slight sheen of the leather accentuate the ink-like intensity of the blue, making the purple undertones pop even under moderate lighting.

Swift: Smooth Radiance

Swift leather, with its micro-grain and smooth texture, absorbs dye like a sponge. On Swift, both colors achieve their purest, most luminous states. Bleu Nuit in Swift has a rich, semi-matte luster that looks exceptionally luxurious, while Bleu Encre in Swift displays a sophisticated, liquid-like depth that showcases the complexity of its purple-blue formulation.

Hardware Pairings: Gold vs. Palladium

The choice of hardware (HW) acts as the final frame for these colors, completely altering their aesthetic temperature and formality.

  • Gold Hardware (GHW): Gold hardware provides a stark, warm contrast. When paired with Bleu Nuit, GHW creates a classic, regal, and highly traditional aesthetic—reminiscent of military dress uniforms. It elevates the bag into a formal statement piece. When paired with Bleu Encre, GHW complements the warm violet undertones of the dye, creating a rich, opulent, and slightly bohemian jewelry-like effect.
  • Palladium Hardware (PHW): Palladium hardware offers a cool, crisp contrast. On Bleu Nuit, PHW accentuates the cold, grey undertones of the midnight blue, resulting in a modern, understated, and highly professional look. It is the ultimate choice for those who want their bag to remain low-key. On Bleu Encre, PHW tones down the warmth of the purple, highlighting the cool indigo notes and lending the bag a sleek, contemporary, and artistic edge.

Market Value and Collectibility

In the secondary market, both colors command strong premiums, but they appeal to different segments of buyers. Bleu Nuit is treated by the market as a "core neutral." Because it serves as a direct alternative to black, its liquidity is incredibly high—it sells quickly because it fits seamlessly into any wardrobe. It holds its value consistently across all sizes, particularly in the highly coveted Birkin 25 and Birkin 30 sizes.

Bleu Encre, as a seasonal release from 2018, is rarer. It appeals directly to collectors who already own standard neutrals (like Noir, Gold, and Etoupe) and are looking to add a sophisticated "color" to their rotation. While it may take slightly longer to find the right buyer compared to Bleu Nuit, its rarity allows sellers to command high premiums from collectors specifically seeking that elusive fountain-pen-ink aesthetic.

Live Examples: Contextualizing Neutrals and Sizes

To understand how these dark blues sit within the broader Hermès pricing and color ecosystem, it is helpful to look at real-world examples of other highly sought-after neutrals and vintage classics currently available in the secondary market.

If you are considering a dark, structured neutral but want to compare it to the ultimate benchmark of black, look to the vintage classics. For instance, the Hermès Birkin 35 Black Veau Ardennes Gold Plated Z Circle Stamp is available for $16,990 at REDELUXE. Veau Ardennes is a discontinued, highly structured leather that showcases how a true black neutral maintains its rigidity and deep pigment over decades, offering a useful point of comparison for those debating between a dark navy like Bleu Nuit and a true vintage Noir.

For those who appreciate deep, organic tones but want to step away from the blue spectrum entirely, consider other archival neutrals. The Hermès Birkin 35 Vert Olive Fjord Palladium Plated R Square Stamp, priced at $16,990 at REDELUXE, demonstrates how deep olive tones can serve a similar utilitarian purpose as Bleu Nuit—offering a dark, sophisticated alternative to black with an earthy, understated elegance in the durable, waterproof Fjord leather.

Conversely, if your preference leans toward modern, lighter neutrals rather than deep midnight tones, the market pricing shifts. The Hermès Pre-owned Hermes Birkin 30 Mushroom Togo Gold Hardware is listed for $22,500 at Madison Avenue Couture. This modern, highly coveted off-white/grey neutral in the popular 30cm size commands a higher premium, illustrating how size (30cm vs. 35cm) and contemporary color trends influence secondary market valuations relative to the classic dark blues and vintage blacks.

What to Verify Before Buying

When purchasing a pre-owned Birkin in either Bleu Nuit or Bleu Encre, a disciplined verification process is essential to protect your investment. Use this checklist before finalizing your wire transfer:

  • Verify the Date Stamp: Bleu Encre was introduced in 2018 (C stamp). While Hermès occasionally re-releases colors in limited runs, a Bleu Encre bag should typically feature a C stamp or later. Bleu Nuit has a wider range of production years; verify the stamp matches the seller's listed year of manufacture.
  • Inspect the Corners for Color Loss: Dark blues are notorious for showing corner wear. Because the leather underneath the dye is naturally lighter, scuffs on Bleu Nuit or Bleu Encre will appear as light grey or white marks. Inspect high-resolution photos of all four bottom corners closely.
  • Request Lighting Consistency: Because both colors are highly reactive to light, ask the seller for photos taken in both direct natural sunlight and overcast/indoor lighting. This prevents any surprises when you unbox the bag.
  • Examine the Hardware: Check for hairline scratches on the hardware plates and turnlock. If the bag is listed as "Store Fresh" or "Like New," the original protective plastics should be intact, though buyers should be aware that keeping plastic on for years can sometimes cause moisture trapping and hardware tarnishing.
  • Confirm the Leather Type: Ensure the leather matches your lifestyle. If you want a structured, scratch-resistant bag that keeps its shape, verify it is Epsom. If you prefer a slouchier, more organic feel, confirm it is Togo or Clemence.

Frequently Asked Questions

Is Bleu Nuit darker than Bleu Saphir?

Yes. Bleu Nuit is significantly darker than Bleu Saphir. Bleu Saphir is a rich, true sapphire blue with distinct navy undertones, but it remains visibly blue in almost all lighting. Bleu Nuit, by contrast, is a midnight blue that frequently appears black in indoor or low-light settings.

Does Bleu Encre look purple in real life?

Bleu Encre does not look like a purple bag, but it has unmistakable violet undertones. In direct sunlight or under warm indoor lighting, these purple undertones become much more prominent, giving the bag a rich, warm indigo appearance. In cool, indirect light, it presents as a deep, ink-like blue.

Which hardware is more popular for these colors?

Gold hardware (GHW) is generally more popular on the secondary market for both colors, as the contrast of gold against deep blue is highly prized by collectors and tends to command a slightly higher resale premium. However, palladium hardware (PHW) is highly sought after by buyers looking for a modern, understated aesthetic.

Does Bleu Nuit show scratches easily?

Scratch visibility depends entirely on the leather rather than the color itself. In Togo or Clemence leather, Bleu Nuit is highly resilient and hides minor scuffs well. In smooth leathers like Swift or Box, scratches will be more visible, though they can often be massaged out by a professional spa treatment.

How can I tell Bleu Nuit apart from Noir (Black) in photos?

Telling them apart in professional studio photos can be difficult due to bright lighting. The easiest way to verify is to check the official Hermès color name on the listing or receipt. Visually, look at the stitching: Bleu Nuit often features matching dark blue thread, which will have a very subtle contrast compared to the stark black thread used on Noir bags.
