How to use #f64d52

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 #79060A
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.

#f64d52, answered

What color is #f64d52?

#f64d52 is a balanced electric red, closest to Indian Red (ΔE2000 7.4). It sits at 358° on the hue wheel with 90% saturation and 63% lightness, which reads as warm.

What is the RGB value of #f64d52?

rgb(246, 77, 82) — 246 red, 77 green and 82 blue out of 255, or 96.5% / 30.2% / 32.2% by channel.

What is #f64d52 in HSL and HSV?

hsl(358, 90%, 63%) and hsv(358, 69%, 96%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #f64d52 a light or a dark color?

It is a mid-tone. Relative luminance is 0.2551 and perceived brightness is 59%, so black text on it reaches 6.10:1.

Should I use black or white text on #f64d52?

Black. It scores 6.10:1 against #f64d52, versus 3.44:1 for white — AA at any size.

Is #f64d52 accessible on a white background?

#f64d52 on white scores 3.44:1, which only clears AA for large text — 18.66px bold or 24px regular and up. Darken it to #EB0C13 to reach 4.5:1, or #B0090E for 7:1.

What is the complementary color of #f64d52?

#4DF6F1 sits directly opposite on the wheel. Softer options are the split-complements #4DF69C and #4DA6F6, which give the same contrast with far less vibration.

What colors go well with #f64d52?

For interface work: #FAF4F4 as the surface, #EDC0C1 for borders, #9B4B4D for secondary text, #05C790 as an accent and #79060A for hover and pressed states. For a palette, the analogous pair #F64DA6 and #F69C4D stays calm, while #4DF6F1 is the loudest partner.

What is #f64d52 in CMYK for printing?

cmyk(0%, 69%, 67%, 4%). 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 #f64d52 warm or cool?

Warm — it scores 18 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #F6754D; nudged cooler, #F84B90.

Which Tailwind color is closest to #f64d52?

The red family — its 500 step is #ef4444, ΔE2000 3.2 away. That is a visible difference, so define #f64d52 as a custom token rather than reaching for the built-in.

How do I use #f64d52 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#f64d52] or text-[#f64d52], 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 #f64d52 with 50% opacity?
