How to use #7f7c39

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

Works well for
  • Headings from 24px up on white
  • Text and icons on dark surfaces
  • Charts, tags and secondary surfaces
  • Headers, footers and dark-mode surfaces
  • Brand accents, badges and data highlights
Use with care
  • Small text on white — under 4.5:1
  • 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
24px / 18.66px bold
Safe as a fill behind white type
No — use #585628
Safe as a 1px border on white
Yes

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 #7f7c39 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.

#7f7c39, answered

What color is #7f7c39?

#7f7c39 is a dark soft yellow, closest to Olive (ΔE2000 6.6). It sits at 57° on the hue wheel with 38% saturation and 36% lightness, which reads as warm.

What is the RGB value of #7f7c39?

rgb(127, 124, 57) — 127 red, 124 green and 57 blue out of 255, or 49.8% / 48.6% / 22.4% by channel.

What is #7f7c39 in HSL and HSV?

hsl(57, 38%, 36%) and hsv(57, 55%, 50%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #7f7c39 a light or a dark color?

It is a mid-tone. Relative luminance is 0.1922 and perceived brightness is 47%, so black text on it reaches 4.84:1.

Should I use black or white text on #7f7c39?

Black. It scores 4.84:1 against #7f7c39, versus 4.33:1 for white — AA at any size.

Is #7f7c39 accessible on a white background?

#7f7c39 on white scores 4.33:1, which only clears AA for large text — 18.66px bold or 24px regular and up. Darken it to #7C7937 to reach 4.5:1, or #5C5A29 for 7:1.

What is the complementary color of #7f7c39?

#393C7F sits directly opposite on the wheel. Softer options are the split-complements #395F7F and #59397F, which give the same contrast with far less vibration.

What colors go well with #7f7c39?

For interface work: #FAFAF4 as the surface, #E6E4C7 for borders, #9B974B for secondary text, #354C83 as an accent and #585628 for hover and pressed states. For a palette, the analogous pair #7F5939 and #5F7F39 stays calm, while #393C7F is the loudest partner.

What is #7f7c39 in CMYK for printing?

cmyk(0%, 2%, 55%, 50%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #7f7c39 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 #7F6239; nudged cooler, #698137.

Which Tailwind color is closest to #7f7c39?

The stone family — its 500 step is #78716c, ΔE2000 19.5 away. That is a visible difference, so define #7f7c39 as a custom token rather than reaching for the built-in.

How do I use #7f7c39 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#7f7c39] or text-[#7f7c39], 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 #7f7c39 with 50% opacity?
