How to use #fd424d

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 #7E0109
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.

#fd424d, answered

What color is #fd424d?

#fd424d is a balanced electric red, closest to Indian Red (ΔE2000 8.5). It sits at 357° on the hue wheel with 98% saturation and 63% lightness, which reads as warm.

What is the RGB value of #fd424d?

rgb(253, 66, 77) — 253 red, 66 green and 77 blue out of 255, or 99.2% / 25.9% / 30.2% by channel.

What is #fd424d in HSL and HSV?

hsl(357, 98%, 63%) and hsv(356, 74%, 99%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #fd424d a light or a dark color?

It is a mid-tone. Relative luminance is 0.2531 and perceived brightness is 59%, so black text on it reaches 6.06:1.

Should I use black or white text on #fd424d?

Black. It scores 6.06:1 against #fd424d, versus 3.46:1 for white — AA at any size.

Is #fd424d accessible on a white background?

#fd424d on white scores 3.46:1, which only clears AA for large text — 18.66px bold or 24px regular and up. Darken it to #EB0210 to reach 4.5:1, or #B3020C for 7:1.

What is the complementary color of #fd424d?

#42FDF2 sits directly opposite on the wheel. Softer options are the split-complements #42FD94 and #42AAFD, which give the same contrast with far less vibration.

What colors go well with #fd424d?

For interface work: #FAF4F5 as the surface, #EDC0C2 for borders, #9B4B4F for secondary text, #00CC8D as an accent and #7E0109 for hover and pressed states. For a palette, the analogous pair #FD42AA and #FD9442 stays calm, while #42FDF2 is the loudest partner.

What is #fd424d in CMYK for printing?

cmyk(0%, 74%, 70%, 1%). 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 #fd424d warm or cool?

Warm — it scores 19 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #FD6A42; nudged cooler, #FF4091.

Which Tailwind color is closest to #fd424d?

The red family — its 500 step is #ef4444, ΔE2000 3.1 away. That is a visible difference, so define #fd424d as a custom token rather than reaching for the built-in.

How do I use #fd424d in Tailwind CSS?

Inline it as an arbitrary value with bg-[#fd424d] or text-[#fd424d], 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 #fd424d with 50% opacity?

rgba(253, 66, 77, 0.5), or #fd424d80 in eight-digit hex. Over white that composites to #FEA1A6; over black, #7F2127.

Is #fd424d a web-safe color?

No. The nearest web-safe colour is #FF3366, ΔE2000 7.9 away. The palette only matters for legacy displays and some email clients now.

What does the color #fd424d mean?
