How to use #ff8564

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
  • Card and section backgrounds
  • Brand accents, badges and data highlights
Use with care
  • Text of any size on white — fails WCAG AA
  • Full-page backgrounds — tiring over long sessions
  • White text placed on it
  • 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
Not as text
Safe as a fill behind white type
No — use #801B00
Safe as a 1px border on white
No — use #FF5D31

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 lightness keeps it airy and approachable.

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.

What each alpha value actually composites to. The top row is #ff8564 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.

#ff8564, answered

What color is #ff8564?

#ff8564 is a light electric red, closest to Coral (ΔE2000 3.8). It sits at 13° on the hue wheel with 100% saturation and 70% lightness, which reads as warm.

What is the RGB value of #ff8564?

rgb(255, 133, 100) — 255 red, 133 green and 100 blue out of 255, or 100% / 52.2% / 39.2% by channel.

What is #ff8564 in HSL and HSV?

hsl(13, 100%, 70%) and hsv(13, 61%, 100%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #ff8564 a light or a dark color?

It is a mid-tone. Relative luminance is 0.3896 and perceived brightness is 69%, so black text on it reaches 8.79:1.

Should I use black or white text on #ff8564?

Black. It scores 8.79:1 against #ff8564, versus 2.39:1 for white — AAA at any size.

Is #ff8564 accessible on a white background?

#ff8564 on white scores 2.39:1, which fails WCAG AA at every size. Darken it to #DE2F00 to reach 4.5:1, or #AB2500 for 7:1.

What is the complementary color of #ff8564?

#64DEFF sits directly opposite on the wheel. Softer options are the split-complements #64FFD3 and #6490FF, which give the same contrast with far less vibration.

What colors go well with #ff8564?

For interface work: #FAF6F4 as the surface, #EDC9C0 for borders, #9B5C4B for secondary text, #00CCC4 as an accent and #801B00 for hover and pressed states. For a palette, the analogous pair #FF6490 and #FFD364 stays calm, while #64DEFF is the loudest partner.

What is #ff8564 in CMYK for printing?

cmyk(0%, 48%, 61%, 0%). 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 #ff8564 warm or cool?

Warm — it scores 10 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #FF9964; nudged cooler, #FF647C.

Which Tailwind color is closest to #ff8564?

The orange family — its 500 step is #f97316, ΔE2000 11.9 away. That is a visible difference, so define #ff8564 as a custom token rather than reaching for the built-in.

How do I use #ff8564 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#ff8564] or text-[#ff8564], 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 #ff8564 with 50% opacity?

rgba(255, 133, 100, 0.5), or #ff856480 in eight-digit hex. Over white that composites to #FFC2B2; over black, #804332.

Is #ff8564 a web-safe color?

No. The nearest web-safe colour is #FF9966, ΔE2000 7.3 away. The palette only matters for legacy displays and some email clients now.

What does the color #ff8564 mean?
