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. #856d13 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 #856d13

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

Works well for
  • Body text and links on white
  • 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
  • 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

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 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.

  • Weight70/100

Transparency

What each alpha value actually composites to. The top row is #856d13 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.

#856d13, answered

What color is #856d13?

#856d13 is a dark electric yellow, closest to Olive (ΔE2000 9.9). It sits at 47° on the hue wheel with 75% saturation and 30% lightness, which reads as warm.

What is the RGB value of #856d13?

rgb(133, 109, 19) — 133 red, 109 green and 19 blue out of 255, or 52.2% / 42.7% / 7.5% by channel.

What is #856d13 in HSL and HSV?

hsl(47, 75%, 30%) and hsv(47, 86%, 52%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #856d13 a light or a dark color?

It is a dark color. Relative luminance is 0.1597 and perceived brightness is 43%, so white text on it reaches 5.01:1.

Should I use black or white text on #856d13?

White. It scores 5.01:1 against #856d13, versus 4.19:1 for black — AA at any size.

Is #856d13 accessible on a white background?

#856d13 on white scores 5.01:1, which clears AA at every size but not AAA.

What is the complementary color of #856d13?

#132B85 sits directly opposite on the wheel. Softer options are the split-complements #136485 and #341385, which give the same contrast with far less vibration.

What colors go well with #856d13?

For interface work: #FAF9F4 as the surface, #EDE3C0 for borders, #9B8A4B for secondary text, #104788 as an accent and #705B10 for hover and pressed states. For a palette, the analogous pair #853413 and #648513 stays calm, while #132B85 is the loudest partner.

What is #856d13 in CMYK for printing?

cmyk(0%, 18%, 86%, 48%). 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 #856d13 warm or cool?

Warm — it scores 14 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #855113; nudged cooler, #748711.

Which Tailwind color is closest to #856d13?

The stone family — its 500 step is #78716c, ΔE2000 21.1 away. That is a visible difference, so define #856d13 as a custom token rather than reaching for the built-in.

How do I use #856d13 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#856d13] or text-[#856d13], 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 #856d13 with 50% opacity?

rgba(133, 109, 19, 0.5), or #856d1380 in eight-digit hex. Over white that composites to #C2B689; over black, #43370A.

Is #856d13 a web-safe color?
