How to use #d52c46

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
  • Brand accents, badges and data highlights
  • Chart series and data categories
Use with care
  • 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

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.

This is a confident chroma: strong enough to lead a brand, restrained enough to live in an interface all day. 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.

#d52c46, answered

What color is #d52c46?

#d52c46 is a balanced vivid red, closest to Crimson (ΔE2000 2.3). It sits at 351° on the hue wheel with 67% saturation and 50% lightness, which reads as warm.

What is the RGB value of #d52c46?

rgb(213, 44, 70) — 213 red, 44 green and 70 blue out of 255, or 83.5% / 17.3% / 27.5% by channel.

What is #d52c46 in HSL and HSV?

hsl(351, 67%, 50%) and hsv(351, 79%, 84%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #d52c46 a light or a dark color?

It is a dark color. Relative luminance is 0.1639 and perceived brightness is 48%, so white text on it reaches 4.91:1.

Should I use black or white text on #d52c46?

White. It scores 4.91:1 against #d52c46, versus 4.28:1 for black — AA at any size.

Is #d52c46 accessible on a white background?

#d52c46 on white scores 4.91:1, which clears AA at every size but not AAA.

What is the complementary color of #d52c46?

#2CD5BB sits directly opposite on the wheel. Softer options are the split-complements #2CD567 and #2C9AD5, which give the same contrast with far less vibration.

What colors go well with #d52c46?

For interface work: #FAF4F5 as the surface, #EDC0C7 for borders, #9B4B57 for secondary text, #1EAE74 as an accent and #6A1522 for hover and pressed states. For a palette, the analogous pair #D52C9A and #D5672C stays calm, while #2CD5BB is the loudest partner.

What is #d52c46 in CMYK for printing?

cmyk(0%, 79%, 67%, 17%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #d52c46 warm or cool?

Warm — it scores 22 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #D54D2C; nudged cooler, #D82A84.

Which Tailwind color is closest to #d52c46?

The rose family — its 500 step is #f43f5e, ΔE2000 8.4 away. That is a visible difference, so define #d52c46 as a custom token rather than reaching for the built-in.

How do I use #d52c46 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#d52c46] or text-[#d52c46], 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 #d52c46 with 50% opacity?

rgba(213, 44, 70, 0.5), or #d52c4680 in eight-digit hex. Over white that composites to #EA96A3; over black, #6B1623.

Is #d52c46 a web-safe color?

No. The nearest web-safe colour is #CC3333, ΔE2000 5.9 away. The palette only matters for legacy displays and some email clients now.
