How to use #445f21

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
  • Text on black or near-black surfaces
  • 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

Safe as a fill behind white type

Safe as a 1px border 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.

#445f21, answered

What color is #445f21?

#445f21 is a dark vivid green, closest to Dark Olive Green (ΔE2000 4.8). It sits at 86° on the hue wheel with 48% saturation and 25% lightness, which reads as neutral.

What is the RGB value of #445f21?

rgb(68, 95, 33) — 68 red, 95 green and 33 blue out of 255, or 26.7% / 37.3% / 12.9% by channel.

What is #445f21 in HSL and HSV?

hsl(86, 48%, 25%) and hsv(86, 65%, 37%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #445f21 a light or a dark color?

It is a dark color. Relative luminance is 0.0952 and perceived brightness is 32%, so white text on it reaches 7.23:1.

Should I use black or white text on #445f21?

White. It scores 7.23:1 against #445f21, versus 2.90:1 for black — AAA at any size.

Is #445f21 accessible on a white background?

#445f21 on white scores 7.23:1, which clears AAA at every size.

What is the complementary color of #445f21?

#3C215F sits directly opposite on the wheel. Softer options are the split-complements #21255F and #5B215F, which give the same contrast with far less vibration.

What colors go well with #445f21?

For interface work: #F8FAF4 as the surface, #D9EAC2 for borders, #789B4B for secondary text, #2B1E62 as an accent and #445F21 for hover and pressed states. For a palette, the analogous pair #5F5B21 and #255F21 stays calm, while #3C215F is the loudest partner.

What is #445f21 in CMYK for printing?

cmyk(28%, 0%, 65%, 63%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #445f21 warm or cool?

Neutral — it scores 47 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #5B5F21; nudged cooler, #2D6020.

Which Tailwind color is closest to #445f21?

The neutral family — its 500 step is #737373, ΔE2000 24.1 away. That is a visible difference, so define #445f21 as a custom token rather than reaching for the built-in.

How do I use #445f21 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#445f21] or text-[#445f21], 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 #445f21 with 50% opacity?

rgba(68, 95, 33, 0.5), or #445f2180 in eight-digit hex. Over white that composites to #A2AF90; over black, #223011.
