How to use #248012

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.

At this chroma the association is amplified — it will dominate anything placed beside it, so give it space and use it sparingly. 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 #248012 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.

#248012, answered

What color is #248012?

#248012 is a dark electric green, closest to Green (ΔE2000 1.6). It sits at 110° on the hue wheel with 75% saturation and 29% lightness, which reads as cool.

What is the RGB value of #248012?

rgb(36, 128, 18) — 36 red, 128 green and 18 blue out of 255, or 14.1% / 50.2% / 7.1% by channel.

What is #248012 in HSL and HSV?

hsl(110, 75%, 29%) and hsv(110, 86%, 50%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #248012 a light or a dark color?

It is a dark color. Relative luminance is 0.1586 and perceived brightness is 39%, so white text on it reaches 5.03:1.

Should I use black or white text on #248012?

White. It scores 5.03:1 against #248012, versus 4.17:1 for black — AA at any size.

Is #248012 accessible on a white background?

#248012 on white scores 5.03:1, which clears AA at every size but not AAA.

What is the complementary color of #248012?

#6E1280 sits directly opposite on the wheel. Softer options are the split-complements #371280 and #80125B, which give the same contrast with far less vibration.

What colors go well with #248012?

For interface work: #F5FAF4 as the surface, #C7EDC0 for borders, #589B4B for secondary text, #530F83 as an accent and #1F7010 for hover and pressed states. For a palette, the analogous pair #5B8012 and #128037 stays calm, while #6E1280 is the loudest partner.

What is #248012 in CMYK for printing?

cmyk(72%, 0%, 86%, 50%). This is a screen-to-ink approximation — a color this saturated sits outside most CMYK gamuts and will print duller than it looks here.

Is #248012 warm or cool?

Cool — it scores 58 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #4C8012; nudged cooler, #118127.

Which Tailwind color is closest to #248012?

The green family — its 500 step is #22c55e, ΔE2000 22 away. That is a visible difference, so define #248012 as a custom token rather than reaching for the built-in.

How do I use #248012 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#248012] or text-[#248012], 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 #248012 with 50% opacity?

rgba(36, 128, 18, 0.5), or #24801280 in eight-digit hex. Over white that composites to #92C089; over black, #124009.

Is #248012 a web-safe color?
