How to use #588955

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 #334F31
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.

#588955, answered

What color is #588955?

#588955 is a dark soft green, closest to Sea Green (ΔE2000 5.9). It sits at 117° on the hue wheel with 23% saturation and 44% lightness, which reads as neutral.

What is the RGB value of #588955?

rgb(88, 137, 85) — 88 red, 137 green and 85 blue out of 255, or 34.5% / 53.7% / 33.3% by channel.

What is #588955 in HSL and HSV?

hsl(117, 23%, 44%) and hsv(117, 38%, 54%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #588955 a light or a dark color?

It is a mid-tone. Relative luminance is 0.2062 and perceived brightness is 47%, so black text on it reaches 5.12:1.

Should I use black or white text on #588955?

Black. It scores 5.12:1 against #588955, versus 4.10:1 for white — AA at any size.

Is #588955 accessible on a white background?

#588955 on white scores 4.10:1, which only clears AA for large text — 18.66px bold or 24px regular and up. Darken it to #527F4F to reach 4.5:1, or #3E603C for 7:1.

What is the complementary color of #588955?

#865589 sits directly opposite on the wheel. Softer options are the split-complements #6C5589 and #895572, which give the same contrast with far less vibration.

What colors go well with #588955?

For interface work: #F6F9F6 as the surface, #CEE0CD for borders, #5B8E58 for secondary text, #7B518D as an accent and #334F31 for hover and pressed states. For a palette, the analogous pair #728955 and #55896C stays calm, while #865589 is the loudest partner.

What is #588955 in CMYK for printing?

cmyk(36%, 0%, 38%, 46%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #588955 warm or cool?

Neutral — it scores 57 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #6B8955; nudged cooler, #538B64.

Which Tailwind color is closest to #588955?

The emerald family — its 500 step is #10b981, ΔE2000 16.4 away. That is a visible difference, so define #588955 as a custom token rather than reaching for the built-in.

How do I use #588955 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#588955] or text-[#588955], 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 #588955 with 50% opacity?
