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.

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

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 #a74f13 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.

#a74f13, answered

What color is #a74f13?

#a74f13 is a dark electric orange, closest to Sienna (ΔE2000 4.8). It sits at 24° on the hue wheel with 80% saturation and 37% lightness, which reads as warm.

What is the RGB value of #a74f13?

rgb(167, 79, 19) — 167 red, 79 green and 19 blue out of 255, or 65.5% / 31% / 7.5% by channel.

What is #a74f13 in HSL and HSV?

hsl(24, 80%, 37%) and hsv(24, 89%, 65%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #a74f13 a light or a dark color?

It is a dark color. Relative luminance is 0.1385 and perceived brightness is 43%, so white text on it reaches 5.57:1.

Should I use black or white text on #a74f13?

White. It scores 5.57:1 against #a74f13, versus 3.77:1 for black — AA at any size.

Is #a74f13 accessible on a white background?

#a74f13 on white scores 5.57:1, which clears AA at every size but not AAA.

What is the complementary color of #a74f13?

#136BA7 sits directly opposite on the wheel. Softer options are the split-complements #13A799 and #1321A7, which give the same contrast with far less vibration.

What colors go well with #a74f13?

For interface work: #FAF7F4 as the surface, #EDD2C0 for borders, #9B6B4B for secondary text, #0F93AB as an accent and #72360D for hover and pressed states. For a palette, the analogous pair #A71321 and #A79913 stays calm, while #136BA7 is the loudest partner.

What is #a74f13 in CMYK for printing?

cmyk(0%, 53%, 89%, 35%). 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 #a74f13 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 #BE5C16; nudged cooler, #A91711.

Which Tailwind color is closest to #a74f13?

The orange family — its 500 step is #f97316, ΔE2000 19.8 away. That is a visible difference, so define #a74f13 as a custom token rather than reaching for the built-in.

How do I use #a74f13 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#a74f13] or text-[#a74f13], 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 #a74f13 with 50% opacity?

rgba(167, 79, 19, 0.5), or #a74f1380 in eight-digit hex. Over white that composites to #D3A789; over black, #54280A.

Is #a74f13 a web-safe color?

No. The nearest web-safe colour is #996600, ΔE2000 13.8 away. The palette only matters for legacy displays and some email clients now.

What does the color #a74f13 mean?
