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

How to use #cfd864

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 #60661A
Safe as a 1px border on white
No — use #929B27

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.

Transparency

What each alpha value actually composites to. The top row is #cfd864 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.

#cfd864, answered

What color is #cfd864?

#cfd864 is a balanced vivid yellow, closest to Khaki (ΔE2000 7.1). It sits at 65° on the hue wheel with 60% saturation and 62% lightness, which reads as warm.

What is the RGB value of #cfd864?

rgb(207, 216, 100) — 207 red, 216 green and 100 blue out of 255, or 81.2% / 84.7% / 39.2% by channel.

What is #cfd864 in HSL and HSV?

hsl(65, 60%, 62%) and hsv(65, 54%, 85%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #cfd864 a light or a dark color?

It is a light color. Relative luminance is 0.6330 and perceived brightness is 80%, so black text on it reaches 13.66:1.

Should I use black or white text on #cfd864?

Black. It scores 13.66:1 against #cfd864, versus 1.54:1 for white — AAA at any size.

Is #cfd864 accessible on a white background?

#cfd864 on white scores 1.54:1, which fails WCAG AA at every size. Darken it to #737A1F to reach 4.5:1, or #545A17 for 7:1.

What is the complementary color of #cfd864?

#6D64D8 sits directly opposite on the wheel. Softer options are the split-complements #6495D8 and #A764D8, which give the same contrast with far less vibration.

What colors go well with #cfd864?

For interface work: #FAFAF4 as the surface, #E9EDC0 for borders, #959B4B for secondary text, #6076DC as an accent and #60661A for hover and pressed states. For a palette, the analogous pair #D8A764 and #95D864 stays calm, while #6D64D8 is the loudest partner.

What is #cfd864 in CMYK for printing?

cmyk(4%, 0%, 54%, 15%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #cfd864 warm or cool?

Warm — it scores 29 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #D8B764; nudged cooler, #A5DA62.

Which Tailwind color is closest to #cfd864?

The lime family — its 500 step is #84cc16, ΔE2000 12.2 away. That is a visible difference, so define #cfd864 as a custom token rather than reaching for the built-in.

How do I use #cfd864 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#cfd864] or text-[#cfd864], 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 #cfd864 with 50% opacity?

rgba(207, 216, 100, 0.5), or #cfd86480 in eight-digit hex. Over white that composites to #E7ECB2; over black, #686C32.

Is #cfd864 a web-safe color?

No. The nearest web-safe colour is #CCCC66, ΔE2000 3.5 away. The palette only matters for legacy displays and some email clients now.

What does the color #cfd864 mean?

As a yellow, it reads optimistic, alert, cheap-and-cheerful. The most visible hue at low light levels, which is why it owns warnings, hazard tape and value retail. At this chroma the effect is amplified — it will dominate whatever sits beside it.

What gradient works with #cfd864?
