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 #fdfca0

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 #7D7C03
Safe as a 1px border on white
No — use #9B9903

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.

#fdfca0, answered

What color is #fdfca0?

#fdfca0 is a light electric yellow, closest to Khaki (ΔE2000 4.9). It sits at 59° on the hue wheel with 96% saturation and 81% lightness, which reads as warm.

What is the RGB value of #fdfca0?

rgb(253, 252, 160) — 253 red, 252 green and 160 blue out of 255, or 99.2% / 98.8% / 62.7% by channel.

What is #fdfca0 in HSL and HSV?

hsl(59, 96%, 81%) and hsv(59, 37%, 99%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #fdfca0 a light or a dark color?

It is a light color. Relative luminance is 0.9304 and perceived brightness is 96%, so black text on it reaches 19.61:1.

Should I use black or white text on #fdfca0?

Black. It scores 19.61:1 against #fdfca0, versus 1.07:1 for white — AAA at any size.

Is #fdfca0 accessible on a white background?

#fdfca0 on white scores 1.07:1, which fails WCAG AA at every size. Darken it to #787703 to reach 4.5:1, or #5A5902 for 7:1.

What is the complementary color of #fdfca0?

#A0A1FD sits directly opposite on the wheel. Softer options are the split-complements #A0CFFD and #CEA0FD, which give the same contrast with far less vibration.

What colors go well with #fdfca0?

For interface work: #FAFAF4 as the surface, #EDECC0 for borders, #9B9A4B for secondary text, #0035CC as an accent and #7D7C03 for hover and pressed states. For a palette, the analogous pair #FDCEA0 and #CFFDA0 stays calm, while #A0A1FD is the loudest partner.

What is #fdfca0 in CMYK for printing?

cmyk(0%, 0%, 37%, 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 #fdfca0 warm or cool?

Warm — it scores 24 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #FDDAA0; nudged cooler, #DCFE9F.

Which Tailwind color is closest to #fdfca0?

The lime family — its 500 step is #84cc16, ΔE2000 20 away. That is a visible difference, so define #fdfca0 as a custom token rather than reaching for the built-in.

How do I use #fdfca0 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#fdfca0] or text-[#fdfca0], 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 #fdfca0 with 50% opacity?

rgba(253, 252, 160, 0.5), or #fdfca080 in eight-digit hex. Over white that composites to #FEFED0; over black, #7F7E50.

Is #fdfca0 a web-safe color?

No. The nearest web-safe colour is #FFFF99, ΔE2000 1.6 away. The palette only matters for legacy displays and some email clients now.

What does the color #fdfca0 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 #fdfca0?

The safest is same-hue elevation: linear-gradient(135deg, #FEFEDC, #fdfca0 45%, #7D7C03). For more colour, a short hue run to #A2FC82 keeps it rich without turning muddy.
