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 #fb8321

Derived from its contrast, chroma and lightness — not from taste.

Works well for
  • 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
  • Text of any size on white — fails WCAG AA
  • Full-page backgrounds — tiring over long sessions
  • Pairing with a same-lightness hue — edges vibrate
Minimum size as text on white
Not as text
Safe as a fill behind white type
No — use #7D3A02
Safe as a 1px border on white
No — use #EF6E04

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 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.

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.

#fb8321, answered

What color is #fb8321?

#fb8321 is a balanced electric orange, closest to Dark Orange (ΔE2000 4.5). It sits at 27° on the hue wheel with 97% saturation and 56% lightness, which reads as warm.

What is the RGB value of #fb8321?

rgb(251, 131, 33) — 251 red, 131 green and 33 blue out of 255, or 98.4% / 51.4% / 12.9% by channel.

What is #fb8321 in HSL and HSV?

hsl(27, 97%, 56%) and hsv(27, 87%, 98%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #fb8321 a light or a dark color?

It is a mid-tone. Relative luminance is 0.3685 and perceived brightness is 67%, so black text on it reaches 8.37:1.

Should I use black or white text on #fb8321?

Black. It scores 8.37:1 against #fb8321, versus 2.51:1 for white — AAA at any size.

Is #fb8321 accessible on a white background?

#fb8321 on white scores 2.51:1, which fails WCAG AA at every size. Darken it to #BD5703 to reach 4.5:1, or #904203 for 7:1.

What is the complementary color of #fb8321?

#2199FB sits directly opposite on the wheel. Softer options are the split-complements #21FBF0 and #212CFB, which give the same contrast with far less vibration.

What colors go well with #fb8321?

For interface work: #FAF7F4 as the surface, #EDD4C0 for borders, #9B6F4B for secondary text, #00A4CC as an accent and #7D3A02 for hover and pressed states. For a palette, the analogous pair #FB212C and #FBF021 stays calm, while #2199FB is the loudest partner.

What is #fb8321 in CMYK for printing?

cmyk(0%, 48%, 87%, 2%). 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 #fb8321 warm or cool?

Warm — it scores 2 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #FB8F3A; nudged cooler, #FD311F.

Which Tailwind color is closest to #fb8321?

The orange family — its 500 step is #f97316, ΔE2000 4.3 away. That is a visible difference, so define #fb8321 as a custom token rather than reaching for the built-in.

How do I use #fb8321 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#fb8321] or text-[#fb8321], 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 #fb8321 with 50% opacity?

rgba(251, 131, 33, 0.5), or #fb832180 in eight-digit hex. Over white that composites to #FDC190; over black, #7E4211.

Is #fb8321 a web-safe color?

No. The nearest web-safe colour is #FF9933, ΔE2000 6.1 away. The palette only matters for legacy displays and some email clients now.

What does the color #fb8321 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 #fb8321?
