How to use #6cb05f

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 #31552A
Safe as a 1px border on white
No — use #5EA451

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.

Transparency

What each alpha value actually composites to. The top row is #6cb05f 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.

#6cb05f, answered

What color is #6cb05f?

#6cb05f is a balanced soft green, closest to Medium Sea Green (ΔE2000 7.1). It sits at 110° on the hue wheel with 34% saturation and 53% lightness, which reads as cool.

What is the RGB value of #6cb05f?

rgb(108, 176, 95) — 108 red, 176 green and 95 blue out of 255, or 42.4% / 69% / 37.3% by channel.

What is #6cb05f in HSL and HSV?

hsl(110, 34%, 53%) and hsv(110, 46%, 69%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #6cb05f a light or a dark color?

It is a mid-tone. Relative luminance is 0.3507 and perceived brightness is 59%, so black text on it reaches 8.01:1.

Should I use black or white text on #6cb05f?

Black. It scores 8.01:1 against #6cb05f, versus 2.62:1 for white — AAA at any size.

Is #6cb05f accessible on a white background?

#6cb05f on white scores 2.62:1, which fails WCAG AA at every size. Darken it to #4B8240 to reach 4.5:1, or #37602F for 7:1.

What is the complementary color of #6cb05f?

#A35FB0 sits directly opposite on the wheel. Softer options are the split-complements #7A5FB0 and #B05F94, which give the same contrast with far less vibration.

What colors go well with #6cb05f?

For interface work: #F6FAF5 as the surface, #CDE4C8 for borders, #589A4C for secondary text, #905AB5 as an accent and #31552A for hover and pressed states. For a palette, the analogous pair #94B05F and #5FB07A stays calm, while #A35FB0 is the loudest partner.

What is #6cb05f in CMYK for printing?

cmyk(39%, 0%, 46%, 31%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #6cb05f warm or cool?

Cool — it scores 58 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #8AB05F; nudged cooler, #5CB26E.

Which Tailwind color is closest to #6cb05f?

The green family — its 500 step is #22c55e, ΔE2000 8.2 away. That is a visible difference, so define #6cb05f as a custom token rather than reaching for the built-in.

How do I use #6cb05f in Tailwind CSS?

Inline it as an arbitrary value with bg-[#6cb05f] or text-[#6cb05f], 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 #6cb05f with 50% opacity?

rgba(108, 176, 95, 0.5), or #6cb05f80 in eight-digit hex. Over white that composites to #B6D8AF; over black, #365830.

Is #6cb05f a web-safe color?

No. The nearest web-safe colour is #669966, ΔE2000 8.5 away. The palette only matters for legacy displays and some email clients now.

What does the color #6cb05f mean?
