How to use #e74635

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 #72170E
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 #e74635 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.

#e74635, answered

What color is #e74635?

#e74635 is a balanced electric red, closest to Red (ΔE2000 6.2). It sits at 6° on the hue wheel with 79% saturation and 56% lightness, which reads as warm.

What is the RGB value of #e74635?

rgb(231, 70, 53) — 231 red, 70 green and 53 blue out of 255, or 90.6% / 27.5% / 20.8% by channel.

What is #e74635 in HSL and HSV?

hsl(6, 79%, 56%) and hsv(6, 77%, 91%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #e74635 a light or a dark color?

It is a mid-tone. Relative luminance is 0.2163 and perceived brightness is 54%, so black text on it reaches 5.33:1.

Should I use black or white text on #e74635?

Black. It scores 5.33:1 against #e74635, versus 3.94:1 for white — AA at any size.

Is #e74635 accessible on a white background?

#e74635 on white scores 3.94:1, which only clears AA for large text — 18.66px bold or 24px regular and up. Darken it to #DE2D1A to reach 4.5:1, or #A72214 for 7:1.

What is the complementary color of #e74635?

#35D6E7 sits directly opposite on the wheel. Softer options are the split-complements #35E79F and #357DE7, which give the same contrast with far less vibration.

What colors go well with #e74635?

For interface work: #FAF5F4 as the surface, #EDC4C0 for borders, #9B524B for secondary text, #11BBA1 as an accent and #72170E for hover and pressed states. For a palette, the analogous pair #E7357D and #E79F35 stays calm, while #35D6E7 is the loudest partner.

What is #e74635 in CMYK for printing?

cmyk(0%, 70%, 77%, 9%). 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 #e74635 warm or cool?

Warm — it scores 14 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #E76735; nudged cooler, #E93364.

Which Tailwind color is closest to #e74635?

The red family — its 500 step is #ef4444, ΔE2000 4.1 away. That is a visible difference, so define #e74635 as a custom token rather than reaching for the built-in.

How do I use #e74635 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#e74635] or text-[#e74635], 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 #e74635 with 50% opacity?
