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 #b8cf52

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
  • Brand accents, badges and data highlights
  • Chart series and data categories
Use with care
  • Text of any size on white — fails WCAG AA
  • Full-page backgrounds — tiring over long sessions
  • 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 #57641C
Safe as a 1px border on white
No — use #869B2B

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 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.

What each alpha value actually composites to. The top row is #b8cf52 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.

#b8cf52, answered

What color is #b8cf52?

#b8cf52 is a balanced vivid green, closest to Yellow Green (ΔE2000 5.3). It sits at 71° on the hue wheel with 57% saturation and 57% lightness, which reads as warm.

What is the RGB value of #b8cf52?

rgb(184, 207, 82) — 184 red, 207 green and 82 blue out of 255, or 72.2% / 81.2% / 32.2% by channel.

What is #b8cf52 in HSL and HSV?

hsl(71, 57%, 57%) and hsv(71, 60%, 81%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #b8cf52 a light or a dark color?

It is a light color. Relative luminance is 0.5543 and perceived brightness is 74%, so black text on it reaches 12.09:1.

Should I use black or white text on #b8cf52?

Black. It scores 12.09:1 against #b8cf52, versus 1.74:1 for white — AAA at any size.

Is #b8cf52 accessible on a white background?

#b8cf52 on white scores 1.74:1, which fails WCAG AA at every size. Darken it to #6A7B22 to reach 4.5:1, or #4F5B19 for 7:1.

What is the complementary color of #b8cf52?

#6952CF sits directly opposite on the wheel. Softer options are the split-complements #527ACF and #A752CF, which give the same contrast with far less vibration.

What colors go well with #b8cf52?

For interface work: #F9FAF4 as the surface, #E4EDC0 for borders, #8C9B4B for secondary text, #4E57D3 as an accent and #57641C for hover and pressed states. For a palette, the analogous pair #CFA752 and #7ACF52 stays calm, while #6952CF is the loudest partner.

What is #b8cf52 in CMYK for printing?

cmyk(11%, 0%, 60%, 19%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #b8cf52 warm or cool?

Warm — it scores 34 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #CFB852; nudged cooler, #8AD150.

Which Tailwind color is closest to #b8cf52?

The lime family — its 500 step is #84cc16, ΔE2000 8.3 away. That is a visible difference, so define #b8cf52 as a custom token rather than reaching for the built-in.

How do I use #b8cf52 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#b8cf52] or text-[#b8cf52], 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 #b8cf52 with 50% opacity?

rgba(184, 207, 82, 0.5), or #b8cf5280 in eight-digit hex. Over white that composites to #DCE7A9; over black, #5C6829.

Is #b8cf52 a web-safe color?

No. The nearest web-safe colour is #CCCC66, ΔE2000 5.5 away. The palette only matters for legacy displays and some email clients now.

What does the color #b8cf52 mean?
