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.

Color scale — 50 to 950

A Tailwind-shaped ramp built around this exact hex. #b6d113 is pinned to step 600; the rest hold its hue and let saturation ease off at the extremes so the pale end never turns neon.

How to use #b6d113

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
  • Thin strokes and 1px borders — they disappear on light UI
  • 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 #66750B
Safe as a 1px border on white
No — use #899E0E

Meaning and mood

What a colour in this family tends to signal, and how this particular chroma and lightness change the reading.

optimisticalertcheap-and-cheerfulvisible

The most visible hue at low light levels, which is why it owns warnings, hazard tape and value retail.

At this chroma the association is amplified — it will dominate anything placed beside it, so give it space and use it sparingly. The low lightness adds weight and formality.

Worth knowing

Almost never passes contrast against white. Treat it as a surface or a marker, not as text.

Transparency

What each alpha value actually composites to. The top row is #b6d113 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.

#b6d113, answered

What color is #b6d113?

#b6d113 is a dark electric yellow, closest to Yellow Green (ΔE2000 6). It sits at 69° on the hue wheel with 83% saturation and 45% lightness, which reads as warm.

What is the RGB value of #b6d113?

rgb(182, 209, 19) — 182 red, 209 green and 19 blue out of 255, or 71.4% / 82% / 7.5% by channel.

What is #b6d113 in HSL and HSV?

hsl(69, 83%, 45%) and hsv(69, 91%, 82%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #b6d113 a light or a dark color?

It is a light color. Relative luminance is 0.5559 and perceived brightness is 74%, so black text on it reaches 12.12:1.

Should I use black or white text on #b6d113?

Black. It scores 12.12:1 against #b6d113, versus 1.73:1 for white — AAA at any size.

Is #b6d113 accessible on a white background?

#b6d113 on white scores 1.73:1, which fails WCAG AA at every size. Darken it to #6D7D0B to reach 4.5:1, or #505C08 for 7:1.

What is the complementary color of #b6d113?

#2E13D1 sits directly opposite on the wheel. Softer options are the split-complements #1357D1 and #8D13D1, which give the same contrast with far less vibration.

What colors go well with #b6d113?

For interface work: #FAFAF4 as the surface, #E6EDC0 for borders, #909B4B for secondary text, #0E24D5 as an accent and #66750B for hover and pressed states. For a palette, the analogous pair #D18D13 and #57D113 stays calm, while #2E13D1 is the loudest partner.

What is #b6d113 in CMYK for printing?

cmyk(13%, 0%, 91%, 18%). This is a screen-to-ink approximation — a color this saturated sits outside most CMYK gamuts and will print duller than it looks here.

Is #b6d113 warm or cool?

Warm — it scores 32 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #D1A613; nudged cooler, #70D311.

Which Tailwind color is closest to #b6d113?

The lime family — its 500 step is #84cc16, ΔE2000 8.3 away. That is a visible difference, so define #b6d113 as a custom token rather than reaching for the built-in.

How do I use #b6d113 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#b6d113] or text-[#b6d113], 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 #b6d113 with 50% opacity?
