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 #fcf06c

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
  • Card and section backgrounds
  • Brand accents, badges and data highlights
Use with care
  • Text of any size on white — fails WCAG AA
  • Full-page backgrounds — tiring over long sessions
  • 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 #7D7303
Safe as a 1px border on white
No — use #A39603

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.

At this chroma the association is amplified — it will dominate anything placed beside it, so give it space and use it sparingly. 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 #fcf06c 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.

#fcf06c, answered

What color is #fcf06c?

#fcf06c is a light electric yellow, closest to Khaki (ΔE2000 5.8). It sits at 55° on the hue wheel with 96% saturation and 71% lightness, which reads as warm.

What is the RGB value of #fcf06c?

rgb(252, 240, 108) — 252 red, 240 green and 108 blue out of 255, or 98.8% / 94.1% / 42.4% by channel.

What is #fcf06c in HSL and HSV?

hsl(55, 96%, 71%) and hsv(55, 57%, 99%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #fcf06c a light or a dark color?

It is a light color. Relative luminance is 0.8410 and perceived brightness is 91%, so black text on it reaches 17.82:1.

Should I use black or white text on #fcf06c?

Black. It scores 17.82:1 against #fcf06c, versus 1.18:1 for white — AAA at any size.

Is #fcf06c accessible on a white background?

#fcf06c on white scores 1.18:1, which fails WCAG AA at every size. Darken it to #807603 to reach 4.5:1, or #625A02 for 7:1.

What is the complementary color of #fcf06c?

#6C78FC sits directly opposite on the wheel. Softer options are the split-complements #6CC0FC and #A86CFC, which give the same contrast with far less vibration.

What colors go well with #fcf06c?

For interface work: #FAFAF4 as the surface, #EDE9C0 for borders, #9B944B for secondary text, #0044CC as an accent and #7D7303 for hover and pressed states. For a palette, the analogous pair #FCA86C and #C0FC6C stays calm, while #6C78FC is the loudest partner.

What is #fcf06c in CMYK for printing?

cmyk(0%, 5%, 57%, 1%). This is a screen-to-ink approximation — a color this saturated sits outside most CMYK gamuts and will print duller than it looks here.

Is #fcf06c warm or cool?

Warm — it scores 21 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #FCC46C; nudged cooler, #D4FE6B.

Which Tailwind color is closest to #fcf06c?

The yellow family — its 500 step is #eab308, ΔE2000 16.9 away. That is a visible difference, so define #fcf06c as a custom token rather than reaching for the built-in.

How do I use #fcf06c in Tailwind CSS?

Inline it as an arbitrary value with bg-[#fcf06c] or text-[#fcf06c], 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 #fcf06c with 50% opacity?

rgba(252, 240, 108, 0.5), or #fcf06c80 in eight-digit hex. Over white that composites to #FEF8B6; over black, #7E7836.

Is #fcf06c a web-safe color?

No. The nearest web-safe colour is #FFFF66, ΔE2000 4.1 away. The palette only matters for legacy displays and some email clients now.

What does the color #fcf06c mean?
