Color scale — 50 to 950

A Tailwind-shaped ramp built around this exact hex. #858e21 is pinned to step 800; the rest hold its hue and let saturation ease off at the extremes so the pale end never turns neon.

How to use #858e21

Derived from its contrast, chroma and lightness — not from taste.

Works well for
  • Headings from 24px up on white
  • Text and icons on dark surfaces
  • Primary buttons and calls to action
  • Focus rings, active and selected states
  • Headers, footers and dark-mode surfaces
  • Brand accents, badges and data highlights
Use with care
  • Small text on white — under 4.5:1
  • Full-page backgrounds — tiring over long sessions
  • Black 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
24px / 18.66px bold
Safe as a fill behind white type
No — use #616718
Safe as a 1px border on white
Yes

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 low lightness adds weight and formality.

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 #858e21 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.

#858e21, answered

What color is #858e21?

#858e21 is a dark vivid yellow, closest to Olive (ΔE2000 5.4). It sits at 65° on the hue wheel with 62% saturation and 34% lightness, which reads as warm.

What is the RGB value of #858e21?

rgb(133, 142, 33) — 133 red, 142 green and 33 blue out of 255, or 52.2% / 55.7% / 12.9% by channel.

What is #858e21 in HSL and HSV?

hsl(65, 62%, 34%) and hsv(65, 77%, 56%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #858e21 a light or a dark color?

It is a mid-tone. Relative luminance is 0.2444 and perceived brightness is 52%, so black text on it reaches 5.89:1.

Should I use black or white text on #858e21?

Black. It scores 5.89:1 against #858e21, versus 3.57:1 for white — AA at any size.

Is #858e21 accessible on a white background?

#858e21 on white scores 3.57:1, which only clears AA for large text — 18.66px bold or 24px regular and up. Darken it to #72791C to reach 4.5:1, or #565C15 for 7:1.

What is the complementary color of #858e21?

#2A218E sits directly opposite on the wheel. Softer options are the split-complements #214E8E and #61218E, which give the same contrast with far less vibration.

What colors go well with #858e21?

For interface work: #FAFAF4 as the surface, #E9EDC0 for borders, #949B4B for secondary text, #1D3191 as an accent and #616718 for hover and pressed states. For a palette, the analogous pair #8E6121 and #4E8E21 stays calm, while #2A218E is the loudest partner.

What is #858e21 in CMYK for printing?

cmyk(6%, 0%, 77%, 44%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #858e21 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 #8E6F21; nudged cooler, #5D901F.

Which Tailwind color is closest to #858e21?

The lime family — its 500 step is #84cc16, ΔE2000 18.8 away. That is a visible difference, so define #858e21 as a custom token rather than reaching for the built-in.

How do I use #858e21 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#858e21] or text-[#858e21], 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 #858e21 with 50% opacity?
