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.

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 low lightness adds weight and formality.

Worth knowing

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

What each alpha value actually composites to. The top row is #af5b1f 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.

#af5b1f, answered

What color is #af5b1f?

#af5b1f is a dark vivid orange, closest to Sienna (ΔE2000 6.4). It sits at 25° on the hue wheel with 70% saturation and 40% lightness, which reads as warm.

What is the RGB value of #af5b1f?

rgb(175, 91, 31) — 175 red, 91 green and 31 blue out of 255, or 68.6% / 35.7% / 12.2% by channel.

What is #af5b1f in HSL and HSV?

hsl(25, 70%, 40%) and hsv(25, 82%, 69%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #af5b1f a light or a dark color?

It is a dark color. Relative luminance is 0.1670 and perceived brightness is 47%, so white text on it reaches 4.84:1.

Should I use black or white text on #af5b1f?

White. It scores 4.84:1 against #af5b1f, versus 4.34:1 for black — AA at any size.

Is #af5b1f accessible on a white background?

#af5b1f on white scores 4.84:1, which clears AA at every size but not AAA.

What is the complementary color of #af5b1f?

#1F73AF sits directly opposite on the wheel. Softer options are the split-complements #1FAFA3 and #1F2BAF, which give the same contrast with far less vibration.

What colors go well with #af5b1f?

For interface work: #FAF7F4 as the surface, #EDD2C0 for borders, #9B6C4B for secondary text, #1B9AB3 as an accent and #6C3813 for hover and pressed states. For a palette, the analogous pair #AF1F2B and #AFA31F stays calm, while #1F73AF is the loudest partner.

What is #af5b1f in CMYK for printing?

cmyk(0%, 48%, 82%, 31%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #af5b1f 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 #C56723; nudged cooler, #B1241D.

Which Tailwind color is closest to #af5b1f?

The orange family — its 500 step is #f97316, ΔE2000 16.2 away. That is a visible difference, so define #af5b1f as a custom token rather than reaching for the built-in.

How do I use #af5b1f in Tailwind CSS?

Inline it as an arbitrary value with bg-[#af5b1f] or text-[#af5b1f], 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 #af5b1f with 50% opacity?

rgba(175, 91, 31, 0.5), or #af5b1f80 in eight-digit hex. Over white that composites to #D7AD8F; over black, #582E10.

Is #af5b1f a web-safe color?

No. The nearest web-safe colour is #996633, ΔE2000 7.6 away. The palette only matters for legacy displays and some email clients now.

What does the color #af5b1f mean?

As a orange, it reads friendly, energetic, affordable. Orange is red with the aggression taken out — approachable, active, and strongly associated with buying and doing. At this chroma the effect is amplified — it will dominate whatever sits beside it.

What gradient works with #af5b1f?

The safest is same-hue elevation: linear-gradient(135deg, #DA7731, #af5b1f 45%, #6C3813). For more colour, a short hue run to #81951A keeps it rich without turning muddy.
