How to use #669338

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
  • 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 #405C23
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.

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

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 #669338 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.

#669338, answered

What color is #669338?

#669338 is a dark soft green, closest to Olive Drab (ΔE2000 3.8). It sits at 90° on the hue wheel with 45% saturation and 40% lightness, which reads as neutral.

What is the RGB value of #669338?

rgb(102, 147, 56) — 102 red, 147 green and 56 blue out of 255, or 40% / 57.6% / 22% by channel.

What is #669338 in HSL and HSV?

hsl(90, 45%, 40%) and hsv(90, 62%, 58%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #669338 a light or a dark color?

It is a mid-tone. Relative luminance is 0.2398 and perceived brightness is 50%, so black text on it reaches 5.80:1.

Should I use black or white text on #669338?

Black. It scores 5.80:1 against #669338, versus 3.62:1 for white — AA at any size.

Is #669338 accessible on a white background?

#669338 on white scores 3.62:1, which only clears AA for large text — 18.66px bold or 24px regular and up. Darken it to #598031 to reach 4.5:1, or #425F24 for 7:1.

What is the complementary color of #669338?

#653893 sits directly opposite on the wheel. Softer options are the split-complements #383893 and #933893, which give the same contrast with far less vibration.

What colors go well with #669338?

For interface work: #F7FAF4 as the surface, #D6E8C4 for borders, #739B4B for secondary text, #4C3497 as an accent and #405C23 for hover and pressed states. For a palette, the analogous pair #939338 and #389338 stays calm, while #653893 is the loudest partner.

What is #669338 in CMYK for printing?

cmyk(31%, 0%, 62%, 42%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #669338 warm or cool?

Neutral — it scores 50 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #879338; nudged cooler, #439536.

Which Tailwind color is closest to #669338?

The green family — its 500 step is #22c55e, ΔE2000 16.4 away. That is a visible difference, so define #669338 as a custom token rather than reaching for the built-in.

How do I use #669338 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#669338] or text-[#669338], 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.
