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.

How to use #504e21

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

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.

What each alpha value actually composites to. The top row is #504e21 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.

#504e21, answered

What color is #504e21?

#504e21 is a deep soft yellow, closest to Dark Olive Green (ΔE2000 11.6). It sits at 57° on the hue wheel with 42% saturation and 22% lightness, which reads as warm.

What is the RGB value of #504e21?

rgb(80, 78, 33) — 80 red, 78 green and 33 blue out of 255, or 31.4% / 30.6% / 12.9% by channel.

What is #504e21 in HSL and HSV?

hsl(57, 42%, 22%) and hsv(57, 59%, 31%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #504e21 a light or a dark color?

It is a dark color. Relative luminance is 0.0726 and perceived brightness is 29%, so white text on it reaches 8.56:1.

Should I use black or white text on #504e21?

White. It scores 8.56:1 against #504e21, versus 2.45:1 for black — AAA at any size.

Is #504e21 accessible on a white background?

#504e21 on white scores 8.56:1, which clears AAA at every size.

What is the complementary color of #504e21?

#212350 sits directly opposite on the wheel. Softer options are the split-complements #213B50 and #372150, which give the same contrast with far less vibration.

What colors go well with #504e21?

For interface work: #FAFAF4 as the surface, #E7E6C5 for borders, #9B974B for secondary text, #1F2E52 as an accent and #5A5825 for hover and pressed states. For a palette, the analogous pair #503721 and #3B5021 stays calm, while #212350 is the loudest partner.

What is #504e21 in CMYK for printing?

cmyk(0%, 3%, 59%, 69%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #504e21 warm or cool?

Warm — it scores 23 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #503D21; nudged cooler, #415120.

Which Tailwind color is closest to #504e21?

The stone family — its 500 step is #78716c, ΔE2000 21.2 away. That is a visible difference, so define #504e21 as a custom token rather than reaching for the built-in.

How do I use #504e21 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#504e21] or text-[#504e21], 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 #504e21 with 50% opacity?

rgba(80, 78, 33, 0.5), or #504e2180 in eight-digit hex. Over white that composites to #A8A790; over black, #282711.

Is #504e21 a web-safe color?
