How to use #b66d39

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
  • Brand accents, badges and data highlights
  • Chart series and data categories
Use with care
  • Small text on white — under 4.5:1
  • Full-page backgrounds — tiring over long sessions
  • 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 #613A1E
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.

friendlyenergeticaffordablesocial

Orange is red with the aggression taken out — approachable, active, and strongly associated with buying and doing.

This is a confident chroma: strong enough to lead a brand, restrained enough to live in an interface all day. The mid lightness keeps it versatile in both themes.

Worth knowing

Hard to make feel premium, and it collides with the "caution" band in status systems.

Transparency

What each alpha value actually composites to. The top row is #b66d39 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.

#b66d39, answered

What color is #b66d39?

#b66d39 is a balanced vivid orange, closest to Chocolate (ΔE2000 6.4). It sits at 25° on the hue wheel with 52% saturation and 47% lightness, which reads as warm.

What is the RGB value of #b66d39?

rgb(182, 109, 57) — 182 red, 109 green and 57 blue out of 255, or 71.4% / 42.7% / 22.4% by channel.

What is #b66d39 in HSL and HSV?

hsl(25, 52%, 47%) and hsv(25, 69%, 71%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #b66d39 a light or a dark color?

It is a mid-tone. Relative luminance is 0.2118 and perceived brightness is 52%, so black text on it reaches 5.24:1.

Should I use black or white text on #b66d39?

Black. It scores 5.24:1 against #b66d39, versus 4.01:1 for white — AA at any size.

Is #b66d39 accessible on a white background?

#b66d39 on white scores 4.01:1, which only clears AA for large text — 18.66px bold or 24px regular and up. Darken it to #AA6635 to reach 4.5:1, or #7C4A27 for 7:1.

What is the complementary color of #b66d39?

#3982B6 sits directly opposite on the wheel. Softer options are the split-complements #39B6AC and #3943B6, which give the same contrast with far less vibration.

What colors go well with #b66d39?

For interface work: #FAF7F4 as the surface, #ECD3C1 for borders, #9B6C4B for secondary text, #2C8CA0 as an accent and #613A1E for hover and pressed states. For a palette, the analogous pair #B63943 and #B6AC39 stays calm, while #3982B6 is the loudest partner.

What is #b66d39 in CMYK for printing?

cmyk(0%, 40%, 69%, 29%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #b66d39 warm or cool?

Warm — it scores 3 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #C47A44; nudged cooler, #B93D37.

Which Tailwind color is closest to #b66d39?

The orange family — its 500 step is #f97316, ΔE2000 13.3 away. That is a visible difference, so define #b66d39 as a custom token rather than reaching for the built-in.

How do I use #b66d39 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#b66d39] or text-[#b66d39], 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 #b66d39 with 50% opacity?
