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

How to use #c6cd91

Derived from its contrast, chroma and lightness — not from taste.

Works well for
  • Text and icons on dark surfaces
  • Charts, tags and secondary surfaces
  • Card and section backgrounds
  • Brand accents, badges and data highlights
Use with care
  • Text of any size on white — fails WCAG AA
  • White text placed on it
  • Thin strokes and 1px borders — they disappear on light UI
  • Pairing with a same-lightness hue — edges vibrate
Minimum size as text on white
Not as text
Safe as a fill behind white type
No — use #525828
Safe as a 1px border on white
No — use #8F9945

Meaning and mood

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

optimisticalertcheap-and-cheerfulvisible

The most visible hue at low light levels, which is why it owns warnings, hazard tape and value retail.

The muted chroma softens the association — it reads considered rather than loud, which suits long-form and data-heavy screens. The lightness keeps it airy and approachable.

Worth knowing

Almost never passes contrast against white. Treat it as a surface or a marker, not as text.

Transparency

What each alpha value actually composites to. The top row is #c6cd91 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.

#c6cd91, answered

What color is #c6cd91?

#c6cd91 is a light soft yellow, closest to Dark Khaki (ΔE2000 7.5). It sits at 67° on the hue wheel with 38% saturation and 69% lightness, which reads as warm.

What is the RGB value of #c6cd91?

rgb(198, 205, 145) — 198 red, 205 green and 145 blue out of 255, or 77.6% / 80.4% / 56.9% by channel.

What is #c6cd91 in HSL and HSV?

hsl(67, 38%, 69%) and hsv(67, 29%, 80%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #c6cd91 a light or a dark color?

It is a light color. Relative luminance is 0.5771 and perceived brightness is 77%, so black text on it reaches 12.54:1.

Should I use black or white text on #c6cd91?

Black. It scores 12.54:1 against #c6cd91, versus 1.67:1 for white — AAA at any size.

Is #c6cd91 accessible on a white background?

#c6cd91 on white scores 1.67:1, which fails WCAG AA at every size. Darken it to #727937 to reach 4.5:1, or #545A29 for 7:1.

What is the complementary color of #c6cd91?

#9891CD sits directly opposite on the wheel. Softer options are the split-complements #91A8CD and #B691CD, which give the same contrast with far less vibration.

What colors go well with #c6cd91?

For interface work: #FAFAF4 as the surface, #E2E5C7 for borders, #929B4B for secondary text, #3C4790 as an accent and #525828 for hover and pressed states. For a palette, the analogous pair #CDB691 and #A8CD91 stays calm, while #9891CD is the loudest partner.

What is #c6cd91 in CMYK for printing?

cmyk(3%, 0%, 29%, 20%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #c6cd91 warm or cool?

Warm — it scores 31 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #CDBE91; nudged cooler, #B0CF8F.

Which Tailwind color is closest to #c6cd91?

The lime family — its 500 step is #84cc16, ΔE2000 16.2 away. That is a visible difference, so define #c6cd91 as a custom token rather than reaching for the built-in.

How do I use #c6cd91 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#c6cd91] or text-[#c6cd91], 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 #c6cd91 with 50% opacity?

rgba(198, 205, 145, 0.5), or #c6cd9180 in eight-digit hex. Over white that composites to #E3E6C8; over black, #636749.

Is #c6cd91 a web-safe color?

No. The nearest web-safe colour is #CCCC99, ΔE2000 2.8 away. The palette only matters for legacy displays and some email clients now.

What does the color #c6cd91 mean?
