How to use #f82c39

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

Works well for
  • Headings from 24px up on white
  • 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
  • Small text on white — under 4.5:1
  • Full-page backgrounds — tiring over long sessions
  • Status meaning — pair it with an icon or label, never colour alone
  • Pairing with a same-lightness hue — edges vibrate
Minimum size as text on white
24px / 18.66px bold
Safe as a fill behind white type
No — use #7B040C
Safe as a 1px border on white
Yes

Meaning and mood

What a colour in this family tends to signal, and how this particular chroma and lightness change the reading.

urgentappetisingboldphysical

Red arrives before the rest of the page does. It raises attention and appetite, which is why it runs food, sport and clearance pricing.

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

It is also the universal error colour. Use it as a brand accent and users may read a warning that is not there.

#f82c39, answered

What color is #f82c39?

#f82c39 is a balanced electric red, closest to Red (ΔE2000 7.9). It sits at 356° on the hue wheel with 94% saturation and 57% lightness, which reads as warm.

What is the RGB value of #f82c39?

rgb(248, 44, 57) — 248 red, 44 green and 57 blue out of 255, or 97.3% / 17.3% / 22.4% by channel.

What is #f82c39 in HSL and HSV?

hsl(356, 94%, 57%) and hsv(356, 82%, 97%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #f82c39 a light or a dark color?

It is a mid-tone. Relative luminance is 0.2205 and perceived brightness is 55%, so black text on it reaches 5.41:1.

Should I use black or white text on #f82c39?

Black. It scores 5.41:1 against #f82c39, versus 3.88:1 for white — AA at any size.

Is #f82c39 accessible on a white background?

#f82c39 on white scores 3.88:1, which only clears AA for large text — 18.66px bold or 24px regular and up. Darken it to #EA0816 to reach 4.5:1, or #B30611 for 7:1.

What is the complementary color of #f82c39?

#2CF8EB sits directly opposite on the wheel. Softer options are the split-complements #2CF885 and #2C9FF8, which give the same contrast with far less vibration.

What colors go well with #f82c39?

For interface work: #FAF4F5 as the surface, #EDC0C3 for borders, #9B4B50 for secondary text, #03C98B as an accent and #7B040C for hover and pressed states. For a palette, the analogous pair #F82C9F and #F8852C stays calm, while #2CF8EB is the loudest partner.

What is #f82c39 in CMYK for printing?

cmyk(0%, 82%, 77%, 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 #f82c39 warm or cool?

Warm — it scores 19 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #F8552C; nudged cooler, #FA2A84.

Which Tailwind color is closest to #f82c39?

The red family — its 500 step is #ef4444, ΔE2000 2.4 away. That is close enough to swap in without anyone noticing.

How do I use #f82c39 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#f82c39] or text-[#f82c39], 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 #f82c39 with 50% opacity?
