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 low lightness adds weight and formality.

Worth knowing

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

Transparency

What each alpha value actually composites to. The top row is #b10285 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.

#b10285, answered

What color is #b10285?

#b10285 is a dark electric magenta / pink, closest to Medium Violet Red (ΔE2000 5.6). It sits at 315° on the hue wheel with 98% saturation and 35% lightness, which reads as warm.

What is the RGB value of #b10285?

rgb(177, 2, 133) — 177 red, 2 green and 133 blue out of 255, or 69.4% / 0.8% / 52.2% by channel.

What is #b10285 in HSL and HSV?

hsl(315, 98%, 35%) and hsv(315, 99%, 69%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #b10285 a light or a dark color?

It is a dark color. Relative luminance is 0.1108 and perceived brightness is 42%, so white text on it reaches 6.53:1.

Should I use black or white text on #b10285?

White. It scores 6.53:1 against #b10285, versus 3.22:1 for black — AA at any size.

Is #b10285 accessible on a white background?

#b10285 on white scores 6.53:1, which clears AA at every size but not AAA.

What is the complementary color of #b10285?

#02B12E sits directly opposite on the wheel. Softer options are the split-complements #2DB102 and #02B186, which give the same contrast with far less vibration.

What colors go well with #b10285?

For interface work: #FAF4F9 as the surface, #EDC0E1 for borders, #9B4B87 for secondary text, #00CC00 as an accent and #7E015F for hover and pressed states. For a palette, the analogous pair #8602B1 and #B1022D stays calm, while #02B12E is the loudest partner.

What is #b10285 in CMYK for printing?

cmyk(0%, 99%, 25%, 31%). 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 #b10285 warm or cool?

Warm — it scores 42 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #B10245; nudged cooler, #9E00B3.

Which Tailwind color is closest to #b10285?

The pink family — its 500 step is #ec4899, ΔE2000 17.9 away. That is a visible difference, so define #b10285 as a custom token rather than reaching for the built-in.

How do I use #b10285 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#b10285] or text-[#b10285], 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 #b10285 with 50% opacity?

rgba(177, 2, 133, 0.5), or #b1028580 in eight-digit hex. Over white that composites to #D881C2; over black, #590143.

Is #b10285 a web-safe color?

No. The nearest web-safe colour is #990099, ΔE2000 7.6 away. The palette only matters for legacy displays and some email clients now.
