How to use #f28b39

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 #783908
Safe as a 1px border on white
No — use #E9700F

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.

What each alpha value actually composites to. The top row is #f28b39 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.

#f28b39, answered

What color is #f28b39?

#f28b39 is a balanced electric orange, closest to Dark Orange (ΔE2000 5). It sits at 27° on the hue wheel with 88% saturation and 59% lightness, which reads as warm.

What is the RGB value of #f28b39?

rgb(242, 139, 57) — 242 red, 139 green and 57 blue out of 255, or 94.9% / 54.5% / 22.4% by channel.

What is #f28b39 in HSL and HSV?

hsl(27, 88%, 59%) and hsv(27, 76%, 95%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #f28b39 a light or a dark color?

It is a mid-tone. Relative luminance is 0.3764 and perceived brightness is 67%, so black text on it reaches 8.53:1.

Should I use black or white text on #f28b39?

Black. It scores 8.53:1 against #f28b39, versus 2.46:1 for white — AAA at any size.

Is #f28b39 accessible on a white background?

#f28b39 on white scores 2.46:1, which fails WCAG AA at every size. Darken it to #B9590C to reach 4.5:1, or #8E4409 for 7:1.

What is the complementary color of #f28b39?

#39A0F2 sits directly opposite on the wheel. Softer options are the split-complements #39F2E8 and #3943F2, which give the same contrast with far less vibration.

What colors go well with #f28b39?

For interface work: #FAF7F4 as the surface, #EDD4C0 for borders, #9B6E4B for secondary text, #09A0C3 as an accent and #783908 for hover and pressed states. For a palette, the analogous pair #F23943 and #F2E839 stays calm, while #39A0F2 is the loudest partner.

What is #f28b39 in CMYK for printing?

cmyk(0%, 43%, 76%, 5%). 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 #f28b39 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 #F49751; nudged cooler, #F44537.

Which Tailwind color is closest to #f28b39?

The orange family — its 500 step is #f97316, ΔE2000 6.2 away. That is a visible difference, so define #f28b39 as a custom token rather than reaching for the built-in.

How do I use #f28b39 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#f28b39] or text-[#f28b39], 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 #f28b39 with 50% opacity?

rgba(242, 139, 57, 0.5), or #f28b3980 in eight-digit hex. Over white that composites to #F9C59C; over black, #79461D.
