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. #bfd90c 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 #bfd90c

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 #6A7907
Safe as a 1px border on white
No — use #889A09

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 #bfd90c 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.

#bfd90c, answered

What color is #bfd90c?

#bfd90c is a dark electric yellow, closest to Yellow Green (ΔE2000 7.4). It sits at 68° on the hue wheel with 90% saturation and 45% lightness, which reads as warm.

What is the RGB value of #bfd90c?

rgb(191, 217, 12) — 191 red, 217 green and 12 blue out of 255, or 74.9% / 85.1% / 4.7% by channel.

What is #bfd90c in HSL and HSV?

hsl(68, 90%, 45%) and hsv(68, 94%, 85%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #bfd90c a light or a dark color?

It is a light color. Relative luminance is 0.6073 and perceived brightness is 77%, so black text on it reaches 13.15:1.

Should I use black or white text on #bfd90c?

Black. It scores 13.15:1 against #bfd90c, versus 1.60:1 for white — AAA at any size.

Is #bfd90c accessible on a white background?

#bfd90c on white scores 1.60:1, which fails WCAG AA at every size. Darken it to #6E7D07 to reach 4.5:1, or #505B05 for 7:1.

What is the complementary color of #bfd90c?

#260CD9 sits directly opposite on the wheel. Softer options are the split-complements #0C59D9 and #8C0CD9, which give the same contrast with far less vibration.

What colors go well with #bfd90c?

For interface work: #FAFAF4 as the surface, #E7EDC0 for borders, #919B4B for secondary text, #0722DE as an accent and #6A7907 for hover and pressed states. For a palette, the analogous pair #D98C0C and #59D90C stays calm, while #260CD9 is the loudest partner.

What is #bfd90c in CMYK for printing?

cmyk(12%, 0%, 95%, 15%). 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 #bfd90c warm or cool?

Warm — it scores 31 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #D9A80C; nudged cooler, #74DB0A.

Which Tailwind color is closest to #bfd90c?

The lime family — its 500 step is #84cc16, ΔE2000 9.7 away. That is a visible difference, so define #bfd90c as a custom token rather than reaching for the built-in.

How do I use #bfd90c in Tailwind CSS?

Inline it as an arbitrary value with bg-[#bfd90c] or text-[#bfd90c], 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 #bfd90c with 50% opacity?

rgba(191, 217, 12, 0.5), or #bfd90c80 in eight-digit hex. Over white that composites to #DFEC86; over black, #606D06.

Is #bfd90c a web-safe color?

No. The nearest web-safe colour is #CCCC00, ΔE2000 5.7 away. The palette only matters for legacy displays and some email clients now.

What does the color #bfd90c 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 #bfd90c?
