How to use #b9df6d

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
  • Card and section backgrounds
  • 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
  • White 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 #4D6917
Safe as a 1px border on white
No — use #769F23

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 lightness keeps it airy and approachable.

Worth knowing

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

What each alpha value actually composites to. The top row is #b9df6d 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.

#b9df6d, answered

What color is #b9df6d?

#b9df6d is a light vivid green, closest to Yellow Green (ΔE2000 6.7). It sits at 80° on the hue wheel with 64% saturation and 65% lightness, which reads as warm.

What is the RGB value of #b9df6d?

rgb(185, 223, 109) — 185 red, 223 green and 109 blue out of 255, or 72.5% / 87.5% / 42.7% by channel.

What is #b9df6d in HSL and HSV?

hsl(80, 64%, 65%) and hsv(80, 51%, 87%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #b9df6d a light or a dark color?

It is a light color. Relative luminance is 0.6419 and perceived brightness is 79%, so black text on it reaches 13.84:1.

Should I use black or white text on #b9df6d?

Black. It scores 13.84:1 against #b9df6d, versus 1.52:1 for white — AAA at any size.

Is #b9df6d accessible on a white background?

#b9df6d on white scores 1.52:1, which fails WCAG AA at every size. Darken it to #5D7E1C to reach 4.5:1, or #476115 for 7:1.

What is the complementary color of #b9df6d?

#936DDF sits directly opposite on the wheel. Softer options are the split-complements #6D80DF and #CC6DDF, which give the same contrast with far less vibration.

What colors go well with #b9df6d?

For interface work: #F8FAF4 as the surface, #DEEDC0 for borders, #809B4B for secondary text, #7469E3 as an accent and #4D6917 for hover and pressed states. For a palette, the analogous pair #DFCC6D and #80DF6D stays calm, while #936DDF is the loudest partner.

What is #b9df6d in CMYK for printing?

cmyk(17%, 0%, 51%, 13%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #b9df6d warm or cool?

Warm — it scores 42 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #DFDB6D; nudged cooler, #8FE16B.

Which Tailwind color is closest to #b9df6d?

The lime family — its 500 step is #84cc16, ΔE2000 9 away. That is a visible difference, so define #b9df6d as a custom token rather than reaching for the built-in.

How do I use #b9df6d in Tailwind CSS?

Inline it as an arbitrary value with bg-[#b9df6d] or text-[#b9df6d], 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 #b9df6d with 50% opacity?

rgba(185, 223, 109, 0.5), or #b9df6d80 in eight-digit hex. Over white that composites to #DCEFB6; over black, #5D7037.

Is #b9df6d a web-safe color?

No. The nearest web-safe colour is #CCCC66, ΔE2000 8.7 away. The palette only matters for legacy displays and some email clients now.

What does the color #b9df6d mean?
