Roughly one man in twelve has some form of colour vision deficiency. If any of the three panels above is hard to tell apart from a neighbouring colour in your palette, add a shape, an icon or a label so the meaning does not rest on hue alone.

Color scale — 50 to 950

  • Headers, footers and dark-mode surfaces
  • Brand accents, badges and data highlights
Use with care
  • Text on black or near-black surfaces
  • Black text placed on it
  • Status meaning — pair it with an icon or label, never colour alone
  • Pairing with a same-lightness hue — edges vibrate
Minimum size as text on white

Meaning and mood

What a colour in this family tends to signal, and how this particular chroma and lightness change the reading.

safegrowingnaturalpermissive

Green means go, well, and grown. It carries finance, sustainability and health with almost no explanation needed.

The muted chroma softens the association — it reads considered rather than loud, which suits long-form and data-heavy screens. The low lightness adds weight and formality.

Worth knowing

Red/green pairs are the most common colour-blindness failure — never let the two carry meaning alone.

What each alpha value actually composites to. The top row is #1b261e over white; the bottom row is the same alpha over a checkerboard, so you can see what survives on a photo or a video.

Bottom row of hexes is the flattened result over white — use those when a design tool refuses transparency, or when you need a solid fallback.

#1b261e, answered

What color is #1b261e?

#1b261e is a deep soft green, closest to Black (ΔE2000 12.2). It sits at 136° on the hue wheel with 17% saturation and 13% lightness, which reads as cool.

What is the RGB value of #1b261e?

rgb(27, 38, 30) — 27 red, 38 green and 30 blue out of 255, or 10.6% / 14.9% / 11.8% by channel.

What is #1b261e in HSL and HSV?

hsl(136, 17%, 13%) and hsv(136, 29%, 15%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #1b261e a light or a dark color?

It is a dark color. Relative luminance is 0.0171 and perceived brightness is 13%, so white text on it reaches 15.64:1.

Should I use black or white text on #1b261e?

White. It scores 15.64:1 against #1b261e, versus 1.34:1 for black — AAA at any size.

Is #1b261e accessible on a white background?

#1b261e on white scores 15.64:1, which clears AAA at every size.

What is the complementary color of #1b261e?

#261B23 sits directly opposite on the wheel. Softer options are the split-complements #231B26 and #261B1D, which give the same contrast with far less vibration.

What colors go well with #1b261e?

For interface work: #F6F9F7 as the surface, #CFDDD3 for borders, #5F866A for secondary text, #271A27 as an accent and #354B3B for hover and pressed states. For a palette, the analogous pair #1D261B and #1B2623 stays calm, while #261B23 is the loudest partner.

What is #1b261e in CMYK for printing?

cmyk(29%, 0%, 21%, 85%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #1b261e warm or cool?

Cool — it scores 59 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #1C261B; nudged cooler, #1A2722.

Which Tailwind color is closest to #1b261e?

The neutral family — its 500 step is #737373, ΔE2000 28.5 away. That is a visible difference, so define #1b261e as a custom token rather than reaching for the built-in.

How do I use #1b261e in Tailwind CSS?

Inline it as an arbitrary value with bg-[#1b261e] or text-[#1b261e], or register the whole ramp under theme.extend.colors.brand so you get bg-brand-500 and friends. The generated 50–950 scale on this page is ready to paste into your config.

What is #1b261e with 50% opacity?

rgba(27, 38, 30, 0.5), or #1b261e80 in eight-digit hex. Over white that composites to #8D938F; over black, #0E130F.

Is #1b261e a web-safe color?
