How to use #788e21

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
  • Primary buttons and calls to action
  • Focus rings, active and selected states
  • Headers, footers and dark-mode surfaces
  • Brand accents, badges and data highlights
Use with care
  • Small text on white — under 4.5:1
  • Full-page backgrounds — tiring over long sessions
  • Black text placed on it
  • Status meaning — pair it with an icon or label, never colour alone
  • 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 #576718
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.

safegrowingnaturalpermissive

Green means go, well, and grown. It carries finance, sustainability and health with almost no explanation needed.

This is a confident chroma: strong enough to lead a brand, restrained enough to live in an interface all day. The low lightness adds weight and formality.

Worth knowing

Red/green pairs are the most common colour-blindness failure — never let the two carry meaning alone.

What each alpha value actually composites to. The top row is #788e21 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.

#788e21, answered

What color is #788e21?

#788e21 is a dark vivid green, closest to Olive Drab (ΔE2000 3.1). It sits at 72° on the hue wheel with 62% saturation and 34% lightness, which reads as warm.

What is the RGB value of #788e21?

rgb(120, 142, 33) — 120 red, 142 green and 33 blue out of 255, or 47.1% / 55.7% / 12.9% by channel.

What is #788e21 in HSL and HSV?

hsl(72, 62%, 34%) and hsv(72, 77%, 56%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #788e21 a light or a dark color?

It is a mid-tone. Relative luminance is 0.2345 and perceived brightness is 50%, so black text on it reaches 5.69:1.

Should I use black or white text on #788e21?

Black. It scores 5.69:1 against #788e21, versus 3.69:1 for white — AA at any size.

Is #788e21 accessible on a white background?

#788e21 on white scores 3.69:1, which only clears AA for large text — 18.66px bold or 24px regular and up. Darken it to #6A7D1D to reach 4.5:1, or #4E5C15 for 7:1.

What is the complementary color of #788e21?

#37218E sits directly opposite on the wheel. Softer options are the split-complements #21418E and #6D218E, which give the same contrast with far less vibration.

What colors go well with #788e21?

For interface work: #F9FAF4 as the surface, #E4EDC0 for borders, #8B9B4B for secondary text, #1D2391 as an accent and #576718 for hover and pressed states. For a palette, the analogous pair #8E6D21 and #418E21 stays calm, while #37218E is the loudest partner.

What is #788e21 in CMYK for printing?

cmyk(16%, 0%, 77%, 44%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #788e21 warm or cool?

Warm — it scores 35 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #8E7C21; nudged cooler, #50901F.

Which Tailwind color is closest to #788e21?

The lime family — its 500 step is #84cc16, ΔE2000 18.1 away. That is a visible difference, so define #788e21 as a custom token rather than reaching for the built-in.

How do I use #788e21 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#788e21] or text-[#788e21], 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.
