How to use #225a2e

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.

#225a2e, answered

What color is #225a2e?

#225a2e is a deep vivid green, closest to Dark Green (ΔE2000 9). It sits at 133° on the hue wheel with 45% saturation and 24% lightness, which reads as cool.

What is the RGB value of #225a2e?

rgb(34, 90, 46) — 34 red, 90 green and 46 blue out of 255, or 13.3% / 35.3% / 18% by channel.

What is #225a2e in HSL and HSV?

hsl(133, 45%, 24%) and hsv(133, 62%, 35%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #225a2e a light or a dark color?

It is a dark color. Relative luminance is 0.0785 and perceived brightness is 29%, so white text on it reaches 8.17:1.

Should I use black or white text on #225a2e?

White. It scores 8.17:1 against #225a2e, versus 2.57:1 for black — AAA at any size.

Is #225a2e accessible on a white background?

#225a2e on white scores 8.17:1, which clears AAA at every size.

What is the complementary color of #225a2e?

#5A224E sits directly opposite on the wheel. Softer options are the split-complements #4A225A and #5A2232, which give the same contrast with far less vibration.

What colors go well with #225a2e?

For interface work: #F4FAF6 as the surface, #C4E9CC for borders, #4B9B5C for secondary text, #5A1F5C as an accent and #235D2F for hover and pressed states. For a palette, the analogous pair #325A22 and #225A4A stays calm, while #5A224E is the loudest partner.

What is #225a2e in CMYK for printing?

cmyk(62%, 0%, 49%, 65%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #225a2e warm or cool?

Cool — it scores 68 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #2A5A22; nudged cooler, #215B43.

Which Tailwind color is closest to #225a2e?

The neutral family — its 500 step is #737373, ΔE2000 25.8 away. That is a visible difference, so define #225a2e as a custom token rather than reaching for the built-in.

How do I use #225a2e in Tailwind CSS?

Inline it as an arbitrary value with bg-[#225a2e] or text-[#225a2e], 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 #225a2e with 50% opacity?

rgba(34, 90, 46, 0.5), or #225a2e80 in eight-digit hex. Over white that composites to #91AD97; over black, #112D17.

Is #225a2e a web-safe color?

No. The nearest web-safe colour is #336633, ΔE2000 4.5 away. The palette only matters for legacy displays and some email clients now.
