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.

Color scale — 50 to 950

How to use #f88421

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 #7C3B04
Safe as a 1px border on white
No — use #EE7107

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.

#f88421, answered

What color is #f88421?

#f88421 is a balanced electric orange, closest to Dark Orange (ΔE2000 4). It sits at 28° on the hue wheel with 94% saturation and 55% lightness, which reads as warm.

What is the RGB value of #f88421?

rgb(248, 132, 33) — 248 red, 132 green and 33 blue out of 255, or 97.3% / 51.8% / 12.9% by channel.

What is #f88421 in HSL and HSV?

hsl(28, 94%, 55%) and hsv(28, 87%, 97%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #f88421 a light or a dark color?

It is a mid-tone. Relative luminance is 0.3657 and perceived brightness is 66%, so black text on it reaches 8.31:1.

Should I use black or white text on #f88421?

Black. It scores 8.31:1 against #f88421, versus 2.53:1 for white — AAA at any size.

Is #f88421 accessible on a white background?

#f88421 on white scores 2.53:1, which fails WCAG AA at every size. Darken it to #BC5A06 to reach 4.5:1, or #8B4204 for 7:1.

What is the complementary color of #f88421?

#2195F8 sits directly opposite on the wheel. Softer options are the split-complements #21F8EF and #212AF8, which give the same contrast with far less vibration.

What colors go well with #f88421?

For interface work: #FAF7F4 as the surface, #EDD4C0 for borders, #9B704B for secondary text, #02A0CA as an accent and #7C3B04 for hover and pressed states. For a palette, the analogous pair #F8212A and #F8EF21 stays calm, while #2195F8 is the loudest partner.

What is #f88421 in CMYK for printing?

cmyk(0%, 47%, 87%, 3%). 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 #f88421 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 #F98E3A; nudged cooler, #FA331F.

Which Tailwind color is closest to #f88421?

The orange family — its 500 step is #f97316, ΔE2000 4.9 away. That is a visible difference, so define #f88421 as a custom token rather than reaching for the built-in.

How do I use #f88421 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#f88421] or text-[#f88421], 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 #f88421 with 50% opacity?

rgba(248, 132, 33, 0.5), or #f8842180 in eight-digit hex. Over white that composites to #FCC290; over black, #7C4211.

Is #f88421 a web-safe color?
