How to use #4d6621

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

Works well for
  • Body text and links on white
  • 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
  • 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

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 #4d6621 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.

#4d6621, answered

What color is #4d6621?

#4d6621 is a dark vivid green, closest to Dark Olive Green (ΔE2000 2.7). It sits at 82° on the hue wheel with 51% saturation and 27% lightness, which reads as neutral.

What is the RGB value of #4d6621?

rgb(77, 102, 33) — 77 red, 102 green and 33 blue out of 255, or 30.2% / 40% / 12.9% by channel.

What is #4d6621 in HSL and HSV?

hsl(82, 51%, 27%) and hsv(82, 68%, 40%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #4d6621 a light or a dark color?

It is a dark color. Relative luminance is 0.1119 and perceived brightness is 35%, so white text on it reaches 6.49:1.

Should I use black or white text on #4d6621?

White. It scores 6.49:1 against #4d6621, versus 3.24:1 for black — AA at any size.

Is #4d6621 accessible on a white background?

#4d6621 on white scores 6.49:1, which clears AA at every size but not AAA.

What is the complementary color of #4d6621?

#3A2166 sits directly opposite on the wheel. Softer options are the split-complements #212B66 and #5D2166, which give the same contrast with far less vibration.

What colors go well with #4d6621?

For interface work: #F8FAF4 as the surface, #DCEBC1 for borders, #7E9B4B for secondary text, #271E69 as an accent and #49601F for hover and pressed states. For a palette, the analogous pair #665D21 and #2B6621 stays calm, while #3A2166 is the loudest partner.

What is #4d6621 in CMYK for printing?

cmyk(25%, 0%, 68%, 60%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #4d6621 warm or cool?

Neutral — it scores 43 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #666621; nudged cooler, #336720.

Which Tailwind color is closest to #4d6621?

The neutral family — its 500 step is #737373, ΔE2000 23.5 away. That is a visible difference, so define #4d6621 as a custom token rather than reaching for the built-in.

How do I use #4d6621 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#4d6621] or text-[#4d6621], 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 #4d6621 with 50% opacity?

rgba(77, 102, 33, 0.5), or #4d662180 in eight-digit hex. Over white that composites to #A6B390; over black, #273311.

Is #4d6621 a web-safe color?

No. The nearest web-safe colour is #666633, ΔE2000 7.9 away. The palette only matters for legacy displays and some email clients now.
