Colour vision deficiency

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

A Tailwind-shaped ramp built around this exact hex. #c9db49 is pinned to step 500; the rest hold its hue and let saturation ease off at the extremes so the pale end never turns neon.

How to use #c9db49

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

Works well for
  • Text and icons on dark surfaces
  • Primary buttons and calls to action
  • Focus rings, active and selected states
  • Brand accents, badges and data highlights
  • Chart series and data categories
Use with care
  • Text of any size on white — fails WCAG AA
  • Full-page backgrounds — tiring over long sessions
  • 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 #606A15
Safe as a 1px border on white
No — use #8B9B1F

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.

This is a confident chroma: strong enough to lead a brand, restrained enough to live in an interface all day. The mid lightness keeps it versatile in both themes.

Worth knowing

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

What each alpha value actually composites to. The top row is #c9db49 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.

#c9db49, answered

What color is #c9db49?

#c9db49 is a balanced vivid yellow, closest to Yellow Green (ΔE2000 7.8). It sits at 67° on the hue wheel with 67% saturation and 57% lightness, which reads as warm.

What is the RGB value of #c9db49?

rgb(201, 219, 73) — 201 red, 219 green and 73 blue out of 255, or 78.8% / 85.9% / 28.6% by channel.

What is #c9db49 in HSL and HSV?

hsl(67, 67%, 57%) and hsv(67, 67%, 86%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #c9db49 a light or a dark color?

It is a light color. Relative luminance is 0.6356 and perceived brightness is 79%, so black text on it reaches 13.71:1.

Should I use black or white text on #c9db49?

Black. It scores 13.71:1 against #c9db49, versus 1.53:1 for white — AAA at any size.

Is #c9db49 accessible on a white background?

#c9db49 on white scores 1.53:1, which fails WCAG AA at every size. Darken it to #707D19 to reach 4.5:1, or #525B12 for 7:1.

What is the complementary color of #c9db49?

#5B49DB sits directly opposite on the wheel. Softer options are the split-complements #4980DB and #A449DB, which give the same contrast with far less vibration.

What colors go well with #c9db49?

For interface work: #FAFAF4 as the surface, #E7EDC0 for borders, #919B4B for secondary text, #4558DF as an accent and #606A15 for hover and pressed states. For a palette, the analogous pair #DBA449 and #80DB49 stays calm, while #5B49DB is the loudest partner.

What is #c9db49 in CMYK for printing?

cmyk(8%, 0%, 67%, 14%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #c9db49 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 #DBB849; nudged cooler, #94DD47.

Which Tailwind color is closest to #c9db49?

The lime family — its 500 step is #84cc16, ΔE2000 10.5 away. That is a visible difference, so define #c9db49 as a custom token rather than reaching for the built-in.

How do I use #c9db49 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#c9db49] or text-[#c9db49], 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 #c9db49 with 50% opacity?

rgba(201, 219, 73, 0.5), or #c9db4980 in eight-digit hex. Over white that composites to #E4EDA4; over black, #656E25.

Is #c9db49 a web-safe color?

No. The nearest web-safe colour is #CCCC33, ΔE2000 5.2 away. The palette only matters for legacy displays and some email clients now.

What does the color #c9db49 mean?
