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. #f0eb91 is pinned to step 300; the rest hold its hue and let saturation ease off at the extremes so the pale end never turns neon.

How to use #f0eb91

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 #706B0F
Safe as a 1px border on white
No — use #9F9816

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 #f0eb91 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.

#f0eb91, answered

What color is #f0eb91?

#f0eb91 is a light electric yellow, closest to Khaki (ΔE2000 1.6). It sits at 57° on the hue wheel with 76% saturation and 76% lightness, which reads as warm.

What is the RGB value of #f0eb91?

rgb(240, 235, 145) — 240 red, 235 green and 145 blue out of 255, or 94.1% / 92.2% / 56.9% by channel.

What is #f0eb91 in HSL and HSV?

hsl(57, 76%, 76%) and hsv(57, 40%, 94%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #f0eb91 a light or a dark color?

It is a light color. Relative luminance is 0.7999 and perceived brightness is 89%, so black text on it reaches 17.00:1.

Should I use black or white text on #f0eb91?

Black. It scores 17.00:1 against #f0eb91, versus 1.24:1 for white — AAA at any size.

Is #f0eb91 accessible on a white background?

#f0eb91 on white scores 1.24:1, which fails WCAG AA at every size. Darken it to #7B7611 to reach 4.5:1, or #5C580D for 7:1.

What is the complementary color of #f0eb91?

#9196F0 sits directly opposite on the wheel. Softer options are the split-complements #91C6F0 and #BB91F0, which give the same contrast with far less vibration.

What colors go well with #f0eb91?

For interface work: #FAFAF4 as the surface, #EDEAC0 for borders, #9B974B for secondary text, #1445B8 as an accent and #706B0F for hover and pressed states. For a palette, the analogous pair #F0BB91 and #C6F091 stays calm, while #9196F0 is the loudest partner.

What is #f0eb91 in CMYK for printing?

cmyk(0%, 2%, 40%, 6%). 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 #f0eb91 warm or cool?

Warm — it scores 22 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #F0C891; nudged cooler, #D3F190.

Which Tailwind color is closest to #f0eb91?

The lime family — its 500 step is #84cc16, ΔE2000 18.5 away. That is a visible difference, so define #f0eb91 as a custom token rather than reaching for the built-in.

How do I use #f0eb91 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#f0eb91] or text-[#f0eb91], 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 #f0eb91 with 50% opacity?

rgba(240, 235, 145, 0.5), or #f0eb9180 in eight-digit hex. Over white that composites to #F8F5C8; over black, #787649.

Is #f0eb91 a web-safe color?

No. The nearest web-safe colour is #FFFF99, ΔE2000 4.3 away. The palette only matters for legacy displays and some email clients now.
