How to use #238021

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.

Transparency

What each alpha value actually composites to. The top row is #238021 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.

#238021, answered

What color is #238021?

#238021 is a dark vivid green, closest to Green (ΔE2000 2.7). It sits at 119° on the hue wheel with 59% saturation and 32% lightness, which reads as cool.

What is the RGB value of #238021?

rgb(35, 128, 33) — 35 red, 128 green and 33 blue out of 255, or 13.7% / 50.2% / 12.9% by channel.

What is #238021 in HSL and HSV?

hsl(119, 59%, 32%) and hsv(119, 74%, 50%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #238021 a light or a dark color?

It is a dark color. Relative luminance is 0.1591 and perceived brightness is 39%, so white text on it reaches 5.02:1.

Should I use black or white text on #238021?

White. It scores 5.02:1 against #238021, versus 4.18:1 for black — AA at any size.

Is #238021 accessible on a white background?

#238021 on white scores 5.02:1, which clears AA at every size but not AAA.

What is the complementary color of #238021?

#7E2180 sits directly opposite on the wheel. Softer options are the split-complements #4F2180 and #802153, which give the same contrast with far less vibration.

What colors go well with #238021?

For interface work: #F4FAF4 as the surface, #C1EDC0 for borders, #4C9B4B for secondary text, #681E83 as an accent and #1C651A for hover and pressed states. For a palette, the analogous pair #538021 and #21804F stays calm, while #7E2180 is the loudest partner.

What is #238021 in CMYK for printing?

cmyk(73%, 0%, 74%, 50%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #238021 warm or cool?

Cool — it scores 62 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #468021; nudged cooler, #1F8241.

Which Tailwind color is closest to #238021?

The emerald family — its 500 step is #10b981, ΔE2000 21.4 away. That is a visible difference, so define #238021 as a custom token rather than reaching for the built-in.

How do I use #238021 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#238021] or text-[#238021], 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 #238021 with 50% opacity?

rgba(35, 128, 33, 0.5), or #23802180 in eight-digit hex. Over white that composites to #91C090; over black, #124011.

Is #238021 a web-safe color?
