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 #bbc124

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 #686B14
Safe as a 1px border on white
No — use #969A1D

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.

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

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 #bbc124 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.

#bbc124, answered

What color is #bbc124?

#bbc124 is a dark vivid yellow, closest to Yellow Green (ΔE2000 9.1). It sits at 62° on the hue wheel with 69% saturation and 45% lightness, which reads as warm.

What is the RGB value of #bbc124?

rgb(187, 193, 36) — 187 red, 193 green and 36 blue out of 255, or 73.3% / 75.7% / 14.1% by channel.

What is #bbc124 in HSL and HSV?

hsl(62, 69%, 45%) and hsv(62, 81%, 76%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #bbc124 a light or a dark color?

It is a mid-tone. Relative luminance is 0.4883 and perceived brightness is 71%, so black text on it reaches 10.77:1.

Should I use black or white text on #bbc124?

Black. It scores 10.77:1 against #bbc124, versus 1.95:1 for white — AAA at any size.

Is #bbc124 accessible on a white background?

#bbc124 on white scores 1.95:1, which fails WCAG AA at every size. Darken it to #747816 to reach 4.5:1, or #575A11 for 7:1.

What is the complementary color of #bbc124?

#2A24C1 sits directly opposite on the wheel. Softer options are the split-complements #246CC1 and #7924C1, which give the same contrast with far less vibration.

What colors go well with #bbc124?

For interface work: #FAFAF4 as the surface, #EBEDC0 for borders, #989B4B for secondary text, #1F43C6 as an accent and #686B14 for hover and pressed states. For a palette, the analogous pair #C17924 and #6CC124 stays calm, while #2A24C1 is the loudest partner.

What is #bbc124 in CMYK for printing?

cmyk(3%, 0%, 81%, 24%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #bbc124 warm or cool?

Warm — it scores 27 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #C18D24; nudged cooler, #82C322.

Which Tailwind color is closest to #bbc124?

The lime family — its 500 step is #84cc16, ΔE2000 11.6 away. That is a visible difference, so define #bbc124 as a custom token rather than reaching for the built-in.

How do I use #bbc124 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#bbc124] or text-[#bbc124], 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 #bbc124 with 50% opacity?

rgba(187, 193, 36, 0.5), or #bbc12480 in eight-digit hex. Over white that composites to #DDE092; over black, #5E6112.

Is #bbc124 a web-safe color?

No. The nearest web-safe colour is #CCCC33, ΔE2000 3.4 away. The palette only matters for legacy displays and some email clients now.

What does the color #bbc124 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 chroma the effect is amplified — it will dominate whatever sits beside it.

What gradient works with #bbc124?
