Color scale — 50 to 950

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.

The muted chroma softens the association — it reads considered rather than loud, which suits long-form and data-heavy screens. The low lightness adds weight and formality.

Worth knowing

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

What each alpha value actually composites to. The top row is #331b32 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.

#331b32, answered

What color is #331b32?

#331b32 is a deep soft magenta / pink, closest to Midnight Blue (ΔE2000 18). It sits at 303° on the hue wheel with 31% saturation and 15% lightness, which reads as neutral.

What is the RGB value of #331b32?

rgb(51, 27, 50) — 51 red, 27 green and 50 blue out of 255, or 20% / 10.6% / 19.6% by channel.

What is #331b32 in HSL and HSV?

hsl(303, 31%, 15%) and hsv(303, 47%, 20%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #331b32 a light or a dark color?

It is a dark color. Relative luminance is 0.0172 and perceived brightness is 15%, so white text on it reaches 15.63:1.

Should I use black or white text on #331b32?

White. It scores 15.63:1 against #331b32, versus 1.34:1 for black — AAA at any size.

Is #331b32 accessible on a white background?

#331b32 on white scores 15.63:1, which clears AAA at every size.

What is the complementary color of #331b32?

#1B331C sits directly opposite on the wheel. Softer options are the split-complements #26331B and #1B3328, which give the same contrast with far less vibration.

What colors go well with #331b32?

For interface work: #FAF5FA as the surface, #E3CAE2 for borders, #964F93 for secondary text, #1F3519 as an accent and #532C52 for hover and pressed states. For a palette, the analogous pair #281B33 and #331B26 stays calm, while #1B331C is the loudest partner.

What is #331b32 in CMYK for printing?

cmyk(0%, 47%, 2%, 80%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #331b32 warm or cool?

Neutral — it scores 49 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #331B29; nudged cooler, #2B1A34.

Which Tailwind color is closest to #331b32?

The zinc family — its 500 step is #71717a, ΔE2000 29.8 away. That is a visible difference, so define #331b32 as a custom token rather than reaching for the built-in.

How do I use #331b32 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#331b32] or text-[#331b32], 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 #331b32 with 50% opacity?

rgba(51, 27, 50, 0.5), or #331b3280 in eight-digit hex. Over white that composites to #998D99; over black, #1A0E19.

Is #331b32 a web-safe color?
