How to use #83bc9d

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

Works well for
  • Text and icons on dark surfaces
  • Charts, tags and secondary surfaces
  • Brand accents, badges and data highlights
  • Chart series and data categories
Use with care
  • Text of any size on white — fails WCAG AA
  • 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
Not as text
Safe as a fill behind white type
No — use #2D533E
Safe as a 1px border on white
No — use #57A178

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 mid lightness keeps it versatile in both themes.

Worth knowing

Red/green pairs are the most common colour-blindness failure — never let the two carry meaning alone.

#83bc9d, answered

What color is #83bc9d?

#83bc9d is a balanced soft green, closest to Dark Sea Green (ΔE2000 5). It sits at 147° on the hue wheel with 30% saturation and 63% lightness, which reads as cool.

What is the RGB value of #83bc9d?

rgb(131, 188, 157) — 131 red, 188 green and 157 blue out of 255, or 51.4% / 73.7% / 61.6% by channel.

What is #83bc9d in HSL and HSV?

hsl(147, 30%, 63%) and hsv(147, 30%, 74%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #83bc9d a light or a dark color?

It is a mid-tone. Relative luminance is 0.4323 and perceived brightness is 66%, so black text on it reaches 9.65:1.

Should I use black or white text on #83bc9d?

Black. It scores 9.65:1 against #83bc9d, versus 2.18:1 for white — AAA at any size.

Is #83bc9d accessible on a white background?

#83bc9d on white scores 2.18:1, which fails WCAG AA at every size. Darken it to #457F60 to reach 4.5:1, or #356249 for 7:1.

What is the complementary color of #83bc9d?

#BC83A2 sits directly opposite on the wheel. Softer options are the split-complements #B983BC and #BC8385, which give the same contrast with far less vibration.

What colors go well with #83bc9d?

For interface work: #F5FAF7 as the surface, #CAE2D5 for borders, #519570 for secondary text, #89437A as an accent and #2D533E for hover and pressed states. For a palette, the analogous pair #85BC83 and #83BCB9 stays calm, while #BC83A2 is the loudest partner.

What is #83bc9d in CMYK for printing?

cmyk(30%, 0%, 17%, 26%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #83bc9d warm or cool?

Cool — it scores 70 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #83BC88; nudged cooler, #81BEB3.

Which Tailwind color is closest to #83bc9d?

The emerald family — its 500 step is #10b981, ΔE2000 10.7 away. That is a visible difference, so define #83bc9d as a custom token rather than reaching for the built-in.

How do I use #83bc9d in Tailwind CSS?

Inline it as an arbitrary value with bg-[#83bc9d] or text-[#83bc9d], 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 #83bc9d with 50% opacity?

rgba(131, 188, 157, 0.5), or #83bc9d80 in eight-digit hex. Over white that composites to #C1DECE; over black, #425E4F.

Is #83bc9d a web-safe color?

No. The nearest web-safe colour is #99CC99, ΔE2000 7.1 away. The palette only matters for legacy displays and some email clients now.

What does the color #83bc9d mean?
