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 #6bae21

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

Works well for
  • Text and icons on dark surfaces
  • Primary buttons and calls to action
  • Focus rings, active and selected states
  • Headers, footers and dark-mode surfaces
  • Brand accents, badges and data highlights
Use with care
  • Text of any size on white — fails WCAG AA
  • Full-page backgrounds — tiring over long sessions
  • 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
Not as text
Safe as a fill behind white type
No — use #426B14
Safe as a 1px border on white
No — use #66A51F

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.

This is a confident chroma: strong enough to lead a brand, restrained enough to live in an interface all day. 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 #6bae21 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.

#6bae21, answered

What color is #6bae21?

#6bae21 is a dark vivid green, closest to Yellow Green (ΔE2000 9.8). It sits at 89° on the hue wheel with 68% saturation and 41% lightness, which reads as neutral.

What is the RGB value of #6bae21?

rgb(107, 174, 33) — 107 red, 174 green and 33 blue out of 255, or 42% / 68.2% / 12.9% by channel.

What is #6bae21 in HSL and HSV?

hsl(89, 68%, 41%) and hsv(89, 81%, 68%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #6bae21 a light or a dark color?

It is a mid-tone. Relative luminance is 0.3351 and perceived brightness is 57%, so black text on it reaches 7.70:1.

Should I use black or white text on #6bae21?

Black. It scores 7.70:1 against #6bae21, versus 2.73:1 for white — AAA at any size.

Is #6bae21 accessible on a white background?

#6bae21 on white scores 2.73:1, which fails WCAG AA at every size. Darken it to #518319 to reach 4.5:1, or #3C6112 for 7:1.

What is the complementary color of #6bae21?

#6421AE sits directly opposite on the wheel. Softer options are the split-complements #2125AE and #AB21AE, which give the same contrast with far less vibration.

What colors go well with #6bae21?

For interface work: #F8FAF4 as the surface, #D7EDC0 for borders, #759B4B for secondary text, #3E1DB2 as an accent and #426B14 for hover and pressed states. For a palette, the analogous pair #AEAB21 and #25AE21 stays calm, while #6421AE is the loudest partner.

What is #6bae21 in CMYK for printing?

cmyk(39%, 0%, 81%, 32%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #6bae21 warm or cool?

Neutral — it scores 49 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #9FAE21; nudged cooler, #36B01F.

Which Tailwind color is closest to #6bae21?

The lime family — its 500 step is #84cc16, ΔE2000 8.6 away. That is a visible difference, so define #6bae21 as a custom token rather than reaching for the built-in.

How do I use #6bae21 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#6bae21] or text-[#6bae21], 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 #6bae21 with 50% opacity?

rgba(107, 174, 33, 0.5), or #6bae2180 in eight-digit hex. Over white that composites to #B5D790; over black, #365711.

Is #6bae21 a web-safe color?

No. The nearest web-safe colour is #669933, ΔE2000 7 away. The palette only matters for legacy displays and some email clients now.

What does the color #6bae21 mean?

As a green, it reads safe, growing, natural. Green means go, well, and grown. It carries finance, sustainability and health with almost no explanation needed. At this chroma the effect is amplified — it will dominate whatever sits beside it.

What gradient works with #6bae21?
