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 #bbc172

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
  • 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 #555927
Safe as a 1px border on white
No — use #929943

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.

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

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 #bbc172 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.

#bbc172, answered

What color is #bbc172?

#bbc172 is a balanced soft yellow, closest to Dark Khaki (ΔE2000 3.9). It sits at 65° on the hue wheel with 39% saturation and 60% lightness, which reads as warm.

What is the RGB value of #bbc172?

rgb(187, 193, 114) — 187 red, 193 green and 114 blue out of 255, or 73.3% / 75.7% / 44.7% by channel.

What is #bbc172 in HSL and HSV?

hsl(65, 39%, 60%) and hsv(65, 41%, 76%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #bbc172 a light or a dark color?

It is a mid-tone. Relative luminance is 0.4992 and perceived brightness is 72%, so black text on it reaches 10.98:1.

Should I use black or white text on #bbc172?

Black. It scores 10.98:1 against #bbc172, versus 1.91:1 for white — AAA at any size.

Is #bbc172 accessible on a white background?

#bbc172 on white scores 1.91:1, which fails WCAG AA at every size. Darken it to #747935 to reach 4.5:1, or #555927 for 7:1.

What is the complementary color of #bbc172?

#7872C1 sits directly opposite on the wheel. Softer options are the split-complements #7293C1 and #A072C1, which give the same contrast with far less vibration.

What colors go well with #bbc172?

For interface work: #FAFAF4 as the surface, #E4E6C6 for borders, #959B4B for secondary text, #6E7DC5 as an accent and #555927 for hover and pressed states. For a palette, the analogous pair #C1A072 and #93C172 stays calm, while #7872C1 is the loudest partner.

What is #bbc172 in CMYK for printing?

cmyk(3%, 0%, 41%, 24%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #bbc172 warm or cool?

Warm — it scores 29 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #C1AA72; nudged cooler, #9EC370.

Which Tailwind color is closest to #bbc172?

The lime family — its 500 step is #84cc16, ΔE2000 13.5 away. That is a visible difference, so define #bbc172 as a custom token rather than reaching for the built-in.

How do I use #bbc172 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#bbc172] or text-[#bbc172], 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 #bbc172 with 50% opacity?

rgba(187, 193, 114, 0.5), or #bbc17280 in eight-digit hex. Over white that composites to #DDE0B9; over black, #5E6139.

Is #bbc172 a web-safe color?

No. The nearest web-safe colour is #CCCC66, ΔE2000 5 away. The palette only matters for legacy displays and some email clients now.

What does the color #bbc172 mean?

As a yellow, it reads optimistic, alert, cheap-and-cheerful. The most visible hue at low light levels, which is why it owns warnings, hazard tape and value retail. At this moderate chroma the association is present but not shouted.

What gradient works with #bbc172?
