How to use #ed2d07

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 #7C1704
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.

Transparency

What each alpha value actually composites to. The top row is #ed2d07 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.

#ed2d07, answered

What color is #ed2d07?

#ed2d07 is a balanced electric red, closest to Red (ΔE2000 3). It sits at 10° on the hue wheel with 94% saturation and 48% lightness, which reads as warm.

What is the RGB value of #ed2d07?

rgb(237, 45, 7) — 237 red, 45 green and 7 blue out of 255, or 92.9% / 17.6% / 2.7% by channel.

What is #ed2d07 in HSL and HSV?

hsl(10, 94%, 48%) and hsv(10, 97%, 93%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #ed2d07 a light or a dark color?

It is a mid-tone. Relative luminance is 0.1990 and perceived brightness is 53%, so black text on it reaches 4.98:1.

Should I use black or white text on #ed2d07?

Black. It scores 4.98:1 against #ed2d07, versus 4.22:1 for white — AA at any size.

Is #ed2d07 accessible on a white background?

#ed2d07 on white scores 4.22:1, which only clears AA for large text — 18.66px bold or 24px regular and up. Darken it to #E32B07 to reach 4.5:1, or #AC2105 for 7:1.

What is the complementary color of #ed2d07?

#07C7ED sits directly opposite on the wheel. Softer options are the split-complements #07EDA0 and #0754ED, which give the same contrast with far less vibration.

What colors go well with #ed2d07?

For interface work: #FAF5F4 as the surface, #EDC7C0 for borders, #9B584B for secondary text, #02CAB9 as an accent and #7C1704 for hover and pressed states. For a palette, the analogous pair #ED0754 and #EDA007 stays calm, while #07C7ED is the loudest partner.

What is #ed2d07 in CMYK for printing?

cmyk(0%, 81%, 97%, 7%). 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 #ed2d07 warm or cool?

Warm — it scores 11 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #ED4B07; nudged cooler, #EF0534.

Which Tailwind color is closest to #ed2d07?

The red family — its 500 step is #ef4444, ΔE2000 9.6 away. That is a visible difference, so define #ed2d07 as a custom token rather than reaching for the built-in.

How do I use #ed2d07 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#ed2d07] or text-[#ed2d07], 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 #ed2d07 with 50% opacity?

rgba(237, 45, 7, 0.5), or #ed2d0780 in eight-digit hex. Over white that composites to #F69683; over black, #771704.

Is #ed2d07 a web-safe color?

No. The nearest web-safe colour is #FF3300, ΔE2000 4.1 away. The palette only matters for legacy displays and some email clients now.

What does the color #ed2d07 mean?
