Roughly one man in twelve has some form of colour vision deficiency. If any of the three panels above is hard to tell apart from a neighbouring colour in your palette, add a shape, an icon or a label so the meaning does not rest on hue alone.

How to use #6dbb6a

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 #2A5828
Safe as a 1px border on white
No — use #4FA64C

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.

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.

#6dbb6a, answered

What color is #6dbb6a?

#6dbb6a is a balanced soft green, closest to Medium Sea Green (ΔE2000 6.6). It sits at 118° on the hue wheel with 37% saturation and 58% lightness, which reads as cool.

What is the RGB value of #6dbb6a?

rgb(109, 187, 106) — 109 red, 187 green and 106 blue out of 255, or 42.7% / 73.3% / 41.6% by channel.

What is #6dbb6a in HSL and HSV?

hsl(118, 37%, 58%) and hsv(118, 43%, 73%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #6dbb6a a light or a dark color?

It is a mid-tone. Relative luminance is 0.3983 and perceived brightness is 62%, so black text on it reaches 8.97:1.

Should I use black or white text on #6dbb6a?

Black. It scores 8.97:1 against #6dbb6a, versus 2.34:1 for white — AAA at any size.

Is #6dbb6a accessible on a white background?

#6dbb6a on white scores 2.34:1, which fails WCAG AA at every size. Darken it to #3F833C to reach 4.5:1, or #30642E for 7:1.

What is the complementary color of #6dbb6a?

#B86ABB sits directly opposite on the wheel. Softer options are the split-complements #906ABB and #BB6A96, which give the same contrast with far less vibration.

What colors go well with #6dbb6a?

For interface work: #F5FAF4 as the surface, #C8E5C7 for borders, #4E9B4B for secondary text, #A666BF as an accent and #2A5828 for hover and pressed states. For a palette, the analogous pair #96BB6A and #6ABB90 stays calm, while #B86ABB is the loudest partner.

What is #6dbb6a in CMYK for printing?

cmyk(42%, 0%, 43%, 27%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #6dbb6a warm or cool?

Cool — it scores 62 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #8BBB6A; nudged cooler, #68BD84.

Which Tailwind color is closest to #6dbb6a?

The green family — its 500 step is #22c55e, ΔE2000 6.3 away. That is a visible difference, so define #6dbb6a as a custom token rather than reaching for the built-in.

How do I use #6dbb6a in Tailwind CSS?

Inline it as an arbitrary value with bg-[#6dbb6a] or text-[#6dbb6a], 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 #6dbb6a with 50% opacity?

rgba(109, 187, 106, 0.5), or #6dbb6a80 in eight-digit hex. Over white that composites to #B6DDB5; over black, #375E35.

Is #6dbb6a a web-safe color?

No. The nearest web-safe colour is #66CC66, ΔE2000 5 away. The palette only matters for legacy displays and some email clients now.

What does the color #6dbb6a mean?
