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.

How to use #af643c

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 #5F3621
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 #af643c 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.

#af643c, answered

What color is #af643c?

#af643c is a balanced vivid orange, closest to Sienna (ΔE2000 6.4). It sits at 21° on the hue wheel with 49% saturation and 46% lightness, which reads as warm.

What is the RGB value of #af643c?

rgb(175, 100, 60) — 175 red, 100 green and 60 blue out of 255, or 68.6% / 39.2% / 23.5% by channel.

What is #af643c in HSL and HSV?

hsl(21, 49%, 46%) and hsv(21, 66%, 69%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #af643c a light or a dark color?

It is a mid-tone. Relative luminance is 0.1855 and perceived brightness is 49%, so black text on it reaches 4.71:1.

Should I use black or white text on #af643c?

Black. It scores 4.71:1 against #af643c, versus 4.46:1 for white — AA at any size.

Is #af643c accessible on a white background?

#af643c on white scores 4.46:1, which only clears AA for large text — 18.66px bold or 24px regular and up. Darken it to #AB623B to reach 4.5:1, or #814A2C for 7:1.

What is the complementary color of #af643c?

#3C87AF sits directly opposite on the wheel. Softer options are the split-complements #3CAF9E and #3C4EAF, which give the same contrast with far less vibration.

What colors go well with #af643c?

For interface work: #FAF6F4 as the surface, #EAD0C2 for borders, #9B674B for secondary text, #30929C as an accent and #5F3621 for hover and pressed states. For a palette, the analogous pair #AF3C4E and #AF9E3C stays calm, while #3C87AF is the loudest partner.

What is #af643c in CMYK for printing?

cmyk(0%, 43%, 66%, 31%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #af643c warm or cool?

Warm — it scores 5 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #BF7645; nudged cooler, #B13A3C.

Which Tailwind color is closest to #af643c?

The orange family — its 500 step is #f97316, ΔE2000 16 away. That is a visible difference, so define #af643c as a custom token rather than reaching for the built-in.

How do I use #af643c in Tailwind CSS?

Inline it as an arbitrary value with bg-[#af643c] or text-[#af643c], 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 #af643c with 50% opacity?

rgba(175, 100, 60, 0.5), or #af643c80 in eight-digit hex. Over white that composites to #D7B29E; over black, #58321E.

Is #af643c a web-safe color?

No. The nearest web-safe colour is #996633, ΔE2000 8.1 away. The palette only matters for legacy displays and some email clients now.

What does the color #af643c mean?
