How to use #548f59

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 #2F5032
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.

Transparency

What each alpha value actually composites to. The top row is #548f59 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.

#548f59, answered

What color is #548f59?

#548f59 is a dark soft green, closest to Sea Green (ΔE2000 5). It sits at 125° on the hue wheel with 26% saturation and 45% lightness, which reads as cool.

What is the RGB value of #548f59?

rgb(84, 143, 89) — 84 red, 143 green and 89 blue out of 255, or 32.9% / 56.1% / 34.9% by channel.

What is #548f59 in HSL and HSV?

hsl(125, 26%, 45%) and hsv(125, 41%, 56%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #548f59 a light or a dark color?

It is a mid-tone. Relative luminance is 0.2225 and perceived brightness is 48%, so black text on it reaches 5.45:1.

Should I use black or white text on #548f59?

Black. It scores 5.45:1 against #548f59, versus 3.85:1 for white — AA at any size.

Is #548f59 accessible on a white background?

#548f59 on white scores 3.85:1, which only clears AA for large text — 18.66px bold or 24px regular and up. Darken it to #4C8251 to reach 4.5:1, or #3A623D for 7:1.

What is the complementary color of #548f59?

#8F548A sits directly opposite on the wheel. Softer options are the split-complements #76548F and #8F546C, which give the same contrast with far less vibration.

What colors go well with #548f59?

For interface work: #F5F9F6 as the surface, #CCE1CD for borders, #55915A for secondary text, #884F94 as an accent and #2F5032 for hover and pressed states. For a palette, the analogous pair #6C8F54 and #548F76 stays calm, while #8F548A is the loudest partner.

What is #548f59 in CMYK for printing?

cmyk(41%, 0%, 38%, 44%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #548f59 warm or cool?

Cool — it scores 61 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #658F54; nudged cooler, #52916E.

Which Tailwind color is closest to #548f59?

The emerald family — its 500 step is #10b981, ΔE2000 14.2 away. That is a visible difference, so define #548f59 as a custom token rather than reaching for the built-in.

How do I use #548f59 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#548f59] or text-[#548f59], 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 #548f59 with 50% opacity?
