Roughly one man in twelve has some form of colour vision deficiency. If any of the three panels above is hard to tell apart from a neighbouring colour in your palette, add a shape, an icon or a label so the meaning does not rest on hue alone.

Color scale — 50 to 950

  • Full-page backgrounds — tiring over long sessions
  • Black text placed on it
  • Pairing with a same-lightness hue — edges vibrate

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.

This is a confident chroma: strong enough to lead a brand, restrained enough to live in an interface all day. The low lightness adds weight and formality.

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.

#250921, answered

What color is #250921?

#250921 is a deep vivid magenta / pink, closest to Black (ΔE2000 17.7). It sits at 309° on the hue wheel with 61% saturation and 9% lightness, which reads as neutral.

What is the RGB value of #250921?

rgb(37, 9, 33) — 37 red, 9 green and 33 blue out of 255, or 14.5% / 3.5% / 12.9% by channel.

What is #250921 in HSL and HSV?

hsl(309, 61%, 9%) and hsv(309, 76%, 15%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #250921 a light or a dark color?

It is a dark color. Relative luminance is 0.0070 and perceived brightness is 9%, so white text on it reaches 18.43:1.

Should I use black or white text on #250921?

White. It scores 18.43:1 against #250921, versus 1.14:1 for black — AAA at any size.

Is #250921 accessible on a white background?

#250921 on white scores 18.43:1, which clears AAA at every size.

What is the complementary color of #250921?

#09250D sits directly opposite on the wheel. Softer options are the split-complements #132509 and #09251B, which give the same contrast with far less vibration.

For interface work: #FAF4FA as the surface, #EDC0E6 for borders, #9B4B8F for secondary text, #0B2608 as an accent and #67195B for hover and pressed states. For a palette, the analogous pair #1B0925 and #250913 stays calm, while #09250D is the loudest partner.

What is #250921 in CMYK for printing?

cmyk(0%, 76%, 11%, 86%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Neutral — it scores 45 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #250917; nudged cooler, #1F0925.

Which Tailwind color is closest to #250921?

The zinc family — its 500 step is #71717a, ΔE2000 34.3 away. That is a visible difference, so define #250921 as a custom token rather than reaching for the built-in.

How do I use #250921 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#250921] or text-[#250921], 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 #250921 with 50% opacity?

rgba(37, 9, 33, 0.5), or #25092180 in eight-digit hex. Over white that composites to #928490; over black, #130511.
