How to use #ef1a5f

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
  • 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 #77082C
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.

expressiveyouthfulwarmconfident

Pink is the fastest way to signal that a product is not another enterprise dashboard. It carries beauty, fashion and culture brands.

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

Strong gendered associations in some markets — test it with the audience you actually have.

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.

#ef1a5f, answered

What color is #ef1a5f?

#ef1a5f is a balanced electric magenta / pink, closest to Crimson (ΔE2000 8.6). It sits at 341° on the hue wheel with 87% saturation and 52% lightness, which reads as warm.

What is the RGB value of #ef1a5f?

rgb(239, 26, 95) — 239 red, 26 green and 95 blue out of 255, or 93.7% / 10.2% / 37.3% by channel.

What is #ef1a5f in HSL and HSV?

hsl(341, 87%, 52%) and hsv(341, 89%, 94%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #ef1a5f a light or a dark color?

It is a mid-tone. Relative luminance is 0.1992 and perceived brightness is 53%, so black text on it reaches 4.98:1.

Should I use black or white text on #ef1a5f?

Black. It scores 4.98:1 against #ef1a5f, versus 4.21:1 for white — AA at any size.

Is #ef1a5f accessible on a white background?

#ef1a5f on white scores 4.21:1, which only clears AA for large text — 18.66px bold or 24px regular and up. Darken it to #E51055 to reach 4.5:1, or #B00C41 for 7:1.

What is the complementary color of #ef1a5f?

#1AEFAA sits directly opposite on the wheel. Softer options are the split-complements #1AEF40 and #1AC9EF, which give the same contrast with far less vibration.

What colors go well with #ef1a5f?

For interface work: #FAF4F6 as the surface, #EDC0CE for borders, #9B4B65 for secondary text, #09C358 as an accent and #77082C for hover and pressed states. For a palette, the analogous pair #EF1AC9 and #EF401A stays calm, while #1AEFAA is the loudest partner.

What is #ef1a5f in CMYK for printing?

cmyk(0%, 89%, 60%, 6%). 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 #ef1a5f warm or cool?

Warm — it scores 27 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #EF231A; nudged cooler, #F118AE.

Which Tailwind color is closest to #ef1a5f?

The rose family — its 500 step is #f43f5e, ΔE2000 5.4 away. That is a visible difference, so define #ef1a5f as a custom token rather than reaching for the built-in.

How do I use #ef1a5f in Tailwind CSS?

Inline it as an arbitrary value with bg-[#ef1a5f] or text-[#ef1a5f], 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 #ef1a5f with 50% opacity?

rgba(239, 26, 95, 0.5), or #ef1a5f80 in eight-digit hex. Over white that composites to #F78DAF; over black, #780D30.

Is #ef1a5f a web-safe color?

No. The nearest web-safe colour is #FF3366, ΔE2000 4.9 away. The palette only matters for legacy displays and some email clients now.

What does the color #ef1a5f mean?
