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.

How to use #ae080f

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

Works well for
  • Body text and links on white
  • Primary buttons and calls to action
  • Focus rings, active and selected states
  • Headers, footers and dark-mode surfaces
  • Brand accents, badges and data highlights
Use with care
  • Text on black or near-black surfaces
  • Full-page backgrounds — tiring over long sessions
  • Black 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

Safe as a fill behind white type

Safe as a 1px border on white

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 low lightness adds weight and formality.

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.

Transparency

What each alpha value actually composites to. The top row is #ae080f 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.

#ae080f, answered

What color is #ae080f?

#ae080f is a dark electric red, closest to Firebrick (ΔE2000 3.5). It sits at 358° on the hue wheel with 91% saturation and 36% lightness, which reads as warm.

What is the RGB value of #ae080f?

rgb(174, 8, 15) — 174 red, 8 green and 15 blue out of 255, or 68.2% / 3.1% / 5.9% by channel.

What is #ae080f in HSL and HSV?

hsl(358, 91%, 36%) and hsv(357, 95%, 68%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #ae080f a light or a dark color?

It is a dark color. Relative luminance is 0.0921 and perceived brightness is 37%, so white text on it reaches 7.39:1.

Should I use black or white text on #ae080f?

White. It scores 7.39:1 against #ae080f, versus 2.84:1 for black — AAA at any size.

Is #ae080f accessible on a white background?

#ae080f on white scores 7.39:1, which clears AAA at every size.

What is the complementary color of #ae080f?

#08AEA7 sits directly opposite on the wheel. Softer options are the split-complements #08AE54 and #0862AE, which give the same contrast with far less vibration.

What colors go well with #ae080f?

For interface work: #FAF4F5 as the surface, #EDC0C2 for borders, #9B4B4E for secondary text, #04C88E as an accent and #7A060A for hover and pressed states. For a palette, the analogous pair #AE0862 and #AE5408 stays calm, while #08AEA7 is the loudest partner.

What is #ae080f in CMYK for printing?

cmyk(0%, 95%, 91%, 32%). 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 #ae080f 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 #AE2F08; nudged cooler, #B0064B.

Which Tailwind color is closest to #ae080f?

The red family — its 500 step is #ef4444, ΔE2000 18.2 away. That is a visible difference, so define #ae080f as a custom token rather than reaching for the built-in.

How do I use #ae080f in Tailwind CSS?

Inline it as an arbitrary value with bg-[#ae080f] or text-[#ae080f], 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 #ae080f with 50% opacity?

rgba(174, 8, 15, 0.5), or #ae080f80 in eight-digit hex. Over white that composites to #D78487; over black, #570408.

Is #ae080f a web-safe color?

No. The nearest web-safe colour is #990000, ΔE2000 4.6 away. The palette only matters for legacy displays and some email clients now.

What does the color #ae080f mean?

As a red, it reads urgent, appetising, bold. 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 effect is amplified — it will dominate whatever sits beside it.

What gradient works with #ae080f?
