How to use #488f4f

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

Works well for
  • Headings from 24px up on white
  • Text and icons on dark surfaces
  • Charts, tags and secondary surfaces
  • Headers, footers and dark-mode surfaces
  • Brand accents, badges and data highlights
Use with care
  • Small text on white — under 4.5:1
  • 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
24px / 18.66px bold
Safe as a fill behind white type
No — use #2B552F
Safe as a 1px border on white
Yes

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.

The muted chroma softens the association — it reads considered rather than loud, which suits long-form and data-heavy screens. 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.

#488f4f, answered

What color is #488f4f?

#488f4f is a dark soft green, closest to Sea Green (ΔE2000 4.6). It sits at 126° on the hue wheel with 33% saturation and 42% lightness, which reads as cool.

What is the RGB value of #488f4f?

rgb(72, 143, 79) — 72 red, 143 green and 79 blue out of 255, or 28.2% / 56.1% / 31% by channel.

What is #488f4f in HSL and HSV?

hsl(126, 33%, 42%) and hsv(126, 50%, 56%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #488f4f a light or a dark color?

It is a mid-tone. Relative luminance is 0.2159 and perceived brightness is 47%, so black text on it reaches 5.32:1.

Should I use black or white text on #488f4f?

Black. It scores 5.32:1 against #488f4f, versus 3.95:1 for white — AA at any size.

Is #488f4f accessible on a white background?

#488f4f on white scores 3.95:1, which only clears AA for large text — 18.66px bold or 24px regular and up. Darken it to #418248 to reach 4.5:1, or #326337 for 7:1.

What is the complementary color of #488f4f?

#8F4888 sits directly opposite on the wheel. Softer options are the split-complements #73488F and #8F4865, which give the same contrast with far less vibration.

What colors go well with #488f4f?

For interface work: #F5FAF5 as the surface, #C9E4CB for borders, #4D9954 for secondary text, #874493 as an accent and #2B552F for hover and pressed states. For a palette, the analogous pair #658F48 and #488F73 stays calm, while #8F4888 is the loudest partner.

What is #488f4f in CMYK for printing?

cmyk(50%, 0%, 45%, 44%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #488f4f warm or cool?

Cool — it scores 64 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #5B8F48; nudged cooler, #469169.

Which Tailwind color is closest to #488f4f?

The emerald family — its 500 step is #10b981, ΔE2000 14.3 away. That is a visible difference, so define #488f4f as a custom token rather than reaching for the built-in.

How do I use #488f4f in Tailwind CSS?

Inline it as an arbitrary value with bg-[#488f4f] or text-[#488f4f], 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 #488f4f with 50% opacity?
