How to use #a37647

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
  • Charts, tags and secondary surfaces
  • Brand accents, badges and data highlights
  • Chart series and data categories
Use with care
  • Small text on white — under 4.5:1
  • 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 #594027
Safe as a 1px border on white

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.

The muted chroma softens the association — it reads considered rather than loud, which suits long-form and data-heavy screens. 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 #a37647 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.

#a37647, answered

What color is #a37647?

#a37647 is a balanced soft orange, closest to Peru (ΔE2000 10). It sits at 31° on the hue wheel with 39% saturation and 46% lightness, which reads as warm.

What is the RGB value of #a37647?

rgb(163, 118, 71) — 163 red, 118 green and 71 blue out of 255, or 63.9% / 46.3% / 27.8% by channel.

What is #a37647 in HSL and HSV?

hsl(31, 39%, 46%) and hsv(31, 56%, 64%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #a37647 a light or a dark color?

It is a mid-tone. Relative luminance is 0.2120 and perceived brightness is 51%, so black text on it reaches 5.24:1.

Should I use black or white text on #a37647?

Black. It scores 5.24:1 against #a37647, versus 4.01:1 for white — AA at any size.

Is #a37647 accessible on a white background?

#a37647 on white scores 4.01:1, which only clears AA for large text — 18.66px bold or 24px regular and up. Darken it to #986E42 to reach 4.5:1, or #715231 for 7:1.

What is the complementary color of #a37647?

#4774A3 sits directly opposite on the wheel. Softer options are the split-complements #47A2A3 and #4847A3, which give the same contrast with far less vibration.

What colors go well with #a37647?

For interface work: #FAF7F4 as the surface, #E6D7C6 for borders, #9B744B for secondary text, #428DA8 as an accent and #594027 for hover and pressed states. For a palette, the analogous pair #A34847 and #A2A347 stays calm, while #4774A3 is the loudest partner.

What is #a37647 in CMYK for printing?

cmyk(0%, 28%, 56%, 36%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #a37647 warm or cool?

Warm — it scores 1 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #B37D51; nudged cooler, #A55345.

Which Tailwind color is closest to #a37647?

The stone family — its 500 step is #78716c, ΔE2000 17.4 away. That is a visible difference, so define #a37647 as a custom token rather than reaching for the built-in.

How do I use #a37647 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#a37647] or text-[#a37647], 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 #a37647 with 50% opacity?

rgba(163, 118, 71, 0.5), or #a3764780 in eight-digit hex. Over white that composites to #D1BBA3; over black, #523B24.
