Color scale — 50 to 950

A Tailwind-shaped ramp built around this exact hex. #30331d is pinned to step 950; the rest hold its hue and let saturation ease off at the extremes so the pale end never turns neon.

How to use #30331d

Derived from its contrast, chroma and lightness — not from taste.

Works well for
  • Body text and links on white
  • Charts, tags and secondary surfaces
  • Headers, footers and dark-mode surfaces
  • Brand accents, badges and data highlights
Use with care
  • Text on black or near-black surfaces
  • Black text placed on it
  • Thin strokes and 1px borders — they disappear on light UI
  • Pairing with a same-lightness hue — edges vibrate
Minimum size as text on white

Safe as a fill behind white type

Meaning and mood

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

optimisticalertcheap-and-cheerfulvisible

The most visible hue at low light levels, which is why it owns warnings, hazard tape and value retail.

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

Almost never passes contrast against white. Treat it as a surface or a marker, not as text.

  • EnergyMedium
  • Weight84/100

Transparency

What each alpha value actually composites to. The top row is #30331d 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.

#30331d, answered

What color is #30331d?

#30331d is a deep soft yellow, closest to Dark Slate Gray (ΔE2000 16.6). It sits at 68° on the hue wheel with 28% saturation and 16% lightness, which reads as warm.

What is the RGB value of #30331d?

rgb(48, 51, 29) — 48 red, 51 green and 29 blue out of 255, or 18.8% / 20% / 11.4% by channel.

What is #30331d in HSL and HSV?

hsl(68, 28%, 16%) and hsv(68, 43%, 20%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #30331d a light or a dark color?

It is a dark color. Relative luminance is 0.0308 and perceived brightness is 19%, so white text on it reaches 12.99:1.

Should I use black or white text on #30331d?

White. It scores 12.99:1 against #30331d, versus 1.62:1 for black — AAA at any size.

Is #30331d accessible on a white background?

#30331d on white scores 12.99:1, which clears AAA at every size.

What is the complementary color of #30331d?

#201D33 sits directly opposite on the wheel. Softer options are the split-complements #1D2533 and #2B1D33, which give the same contrast with far less vibration.

What colors go well with #30331d?

For interface work: #F9F9F5 as the surface, #DEE1CB for borders, #8A9253 for secondary text, #1B1E35 as an accent and #4C512E for hover and pressed states. For a palette, the analogous pair #332B1D and #25331D stays calm, while #201D33 is the loudest partner.

What is #30331d in CMYK for printing?

cmyk(6%, 0%, 43%, 80%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #30331d warm or cool?

Warm — it scores 36 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #332E1D; nudged cooler, #28341C.

Which Tailwind color is closest to #30331d?

The stone family — its 500 step is #78716c, ΔE2000 25.4 away. That is a visible difference, so define #30331d as a custom token rather than reaching for the built-in.

How do I use #30331d in Tailwind CSS?

Inline it as an arbitrary value with bg-[#30331d] or text-[#30331d], 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 #30331d with 50% opacity?

rgba(48, 51, 29, 0.5), or #30331d80 in eight-digit hex. Over white that composites to #98998E; over black, #181A0F.

Is #30331d a web-safe color?

No. The nearest web-safe colour is #333333, ΔE2000 11.8 away. The palette only matters for legacy displays and some email clients now.
