Meaning and mood

What a colour in this family tends to signal, and how this particular chroma and lightness change the reading.

creativepremiummodernimaginative

Violet sits between the warmth of red and the calm of blue, so it reads as inventive without reading as risky. Current shorthand for software craft.

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

Deep violets swallow detail on screens with poor gamma; check it on a cheap laptop panel.

What each alpha value actually composites to. The top row is #37293d 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.

#37293d, answered

What color is #37293d?

#37293d is a deep soft violet, closest to Black (ΔE2000 17.9). It sits at 282° on the hue wheel with 20% saturation and 20% lightness, which reads as neutral.

What is the RGB value of #37293d?

rgb(55, 41, 61) — 55 red, 41 green and 61 blue out of 255, or 21.6% / 16.1% / 23.9% by channel.

What is #37293d in HSL and HSV?

hsl(282, 20%, 20%) and hsv(282, 33%, 24%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

It is a dark color. Relative luminance is 0.0274 and perceived brightness is 19%, so white text on it reaches 13.57:1.

Should I use black or white text on #37293d?

White. It scores 13.57:1 against #37293d, versus 1.55:1 for black — AAA at any size.

Is #37293d accessible on a white background?

#37293d on white scores 13.57:1, which clears AAA at every size.

What is the complementary color of #37293d?

#2F3D29 sits directly opposite on the wheel. Softer options are the split-complements #393D29 and #293D2D, which give the same contrast with far less vibration.

What colors go well with #37293d?

For interface work: #F8F6F9 as the surface, #D9CEDE for borders, #7C5C89 for secondary text, #343F27 as an accent and #45334C for hover and pressed states. For a palette, the analogous pair #2D293D and #3D2939 stays calm, while #2F3D29 is the loudest partner.

What is #37293d in CMYK for printing?

cmyk(10%, 33%, 0%, 76%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Neutral — it scores 56 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #3D293C; nudged cooler, #2F283E.

Which Tailwind color is closest to #37293d?

The zinc family — its 500 step is #71717a, ΔE2000 25.3 away. That is a visible difference, so define #37293d as a custom token rather than reaching for the built-in.

How do I use #37293d in Tailwind CSS?

Inline it as an arbitrary value with bg-[#37293d] or text-[#37293d], 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 #37293d with 50% opacity?

rgba(55, 41, 61, 0.5), or #37293d80 in eight-digit hex. Over white that composites to #9B949E; over black, #1C151F.

Is #37293d a web-safe color?
