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 #fff80f

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 #807C00
Safe as a 1px border on white
No — use #9E9900

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 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.

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.

#fff80f, answered

What color is #fff80f?

#fff80f is a balanced electric yellow, closest to Yellow (ΔE2000 1.8). It sits at 58° on the hue wheel with 100% saturation and 53% lightness, which reads as warm.

What is the RGB value of #fff80f?

rgb(255, 248, 15) — 255 red, 248 green and 15 blue out of 255, or 100% / 97.3% / 5.9% by channel.

What is #fff80f in HSL and HSV?

hsl(58, 100%, 53%) and hsv(58, 94%, 100%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #fff80f a light or a dark color?

It is a light color. Relative luminance is 0.8843 and perceived brightness is 92%, so black text on it reaches 18.69:1.

Should I use black or white text on #fff80f?

Black. It scores 18.69:1 against #fff80f, versus 1.12:1 for white — AAA at any size.

Is #fff80f accessible on a white background?

#fff80f on white scores 1.12:1, which fails WCAG AA at every size. Darken it to #7A7600 to reach 4.5:1, or #5B5900 for 7:1.

What is the complementary color of #fff80f?

#0F16FF sits directly opposite on the wheel. Softer options are the split-complements #0F8EFF and #800FFF, which give the same contrast with far less vibration.

What colors go well with #fff80f?

For interface work: #FAFAF4 as the surface, #EDEBC0 for borders, #9B994B for secondary text, #0F52FF as an accent and #807C00 for hover and pressed states. For a palette, the analogous pair #FF800F and #8EFF0F stays calm, while #0F16FF is the loudest partner.

What is #fff80f in CMYK for printing?

cmyk(0%, 3%, 94%, 0%). 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 #fff80f 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 #FFB80F; nudged cooler, #AEFF0F.

Which Tailwind color is closest to #fff80f?

The yellow family — its 500 step is #eab308, ΔE2000 19 away. That is a visible difference, so define #fff80f as a custom token rather than reaching for the built-in.

How do I use #fff80f in Tailwind CSS?

Inline it as an arbitrary value with bg-[#fff80f] or text-[#fff80f], 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 #fff80f with 50% opacity?

rgba(255, 248, 15, 0.5), or #fff80f80 in eight-digit hex. Over white that composites to #FFFC87; over black, #807C08.

Is #fff80f a web-safe color?

No. The nearest web-safe colour is #FFFF00, ΔE2000 1.8 away. The palette only matters for legacy displays and some email clients now.

What does the color #fff80f 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 #fff80f?

The safest is same-hue elevation: linear-gradient(135deg, #FFFA4C, #fff80f 45%, #807C00). For more colour, a short hue run to #43EF00 keeps it rich without turning muddy.
