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

  • Text on black or near-black surfaces
  • 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.

friendlyenergeticaffordablesocial

Orange is red with the aggression taken out — approachable, active, and strongly associated with buying and doing.

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

Hard to make feel premium, and it collides with the "caution" band in status systems.

What each alpha value actually composites to. The top row is #331d07 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.

Very dark values collapse into each other on cheap panels — leave more lightness between your darkest steps than the numbers suggest.

#331d07, answered

What color is #331d07?

#331d07 is a deep electric orange, closest to Black (ΔE2000 16.4). It sits at 30° on the hue wheel with 76% saturation and 11% lightness, which reads as warm.

What is the RGB value of #331d07?

rgb(51, 29, 7) — 51 red, 29 green and 7 blue out of 255, or 20% / 11.4% / 2.7% by channel.

What is #331d07 in HSL and HSV?

hsl(30, 76%, 11%) and hsv(30, 86%, 20%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #331d07 a light or a dark color?

It is a dark color. Relative luminance is 0.0160 and perceived brightness is 14%, so white text on it reaches 15.91:1.

Should I use black or white text on #331d07?

White. It scores 15.91:1 against #331d07, versus 1.32:1 for black — AAA at any size.

Is #331d07 accessible on a white background?

#331d07 on white scores 15.91:1, which clears AAA at every size.

What is the complementary color of #331d07?

#071D33 sits directly opposite on the wheel. Softer options are the split-complements #073333 and #070733, which give the same contrast with far less vibration.

What colors go well with #331d07?

For interface work: #FAF7F4 as the surface, #EDD6C0 for borders, #9B734B for secondary text, #062934 as an accent and #70400F for hover and pressed states. For a palette, the analogous pair #330707 and #333307 stays calm, while #071D33 is the loudest partner.

What is #331d07 in CMYK for printing?

cmyk(0%, 43%, 86%, 80%). 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 #331d07 warm or cool?

Warm — it scores 0 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #4A260A; nudged cooler, #340C06.

Which Tailwind color is closest to #331d07?

The stone family — its 500 step is #78716c, ΔE2000 29.1 away. That is a visible difference, so define #331d07 as a custom token rather than reaching for the built-in.

How do I use #331d07 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#331d07] or text-[#331d07], 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 #331d07 with 50% opacity?

rgba(51, 29, 7, 0.5), or #331d0780 in eight-digit hex. Over white that composites to #998E83; over black, #1A0F04.

Is #331d07 a web-safe color?
