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 #bcfe3f

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 #537F01
Safe as a 1px border on white
No — use #6BA301

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.

At this chroma the association is amplified — it will dominate anything placed beside it, so give it space and use it sparingly. 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.

Transparency

What each alpha value actually composites to. The top row is #bcfe3f 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.

#bcfe3f, answered

What color is #bcfe3f?

#bcfe3f is a balanced electric green, closest to Green Yellow (ΔE2000 1.9). It sits at 81° on the hue wheel with 99% saturation and 62% lightness, which reads as neutral.

What is the RGB value of #bcfe3f?

rgb(188, 254, 63) — 188 red, 254 green and 63 blue out of 255, or 73.7% / 99.6% / 24.7% by channel.

What is #bcfe3f in HSL and HSV?

hsl(81, 99%, 62%) and hsv(81, 75%, 100%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #bcfe3f a light or a dark color?

It is a light color. Relative luminance is 0.8193 and perceived brightness is 87%, so black text on it reaches 17.39:1.

Should I use black or white text on #bcfe3f?

Black. It scores 17.39:1 against #bcfe3f, versus 1.21:1 for white — AAA at any size.

Is #bcfe3f accessible on a white background?

#bcfe3f on white scores 1.21:1, which fails WCAG AA at every size. Darken it to #548001 to reach 4.5:1, or #406100 for 7:1.

What is the complementary color of #bcfe3f?

#813FFE sits directly opposite on the wheel. Softer options are the split-complements #3F5DFE and #E03FFE, which give the same contrast with far less vibration.

What colors go well with #bcfe3f?

For interface work: #F8FAF4 as the surface, #DDEDC0 for borders, #7F9B4B for secondary text, #513EFF as an accent and #537F01 for hover and pressed states. For a palette, the analogous pair #FEE03F and #5DFE3F stays calm, while #813FFE is the loudest partner.

What is #bcfe3f in CMYK for printing?

cmyk(26%, 0%, 75%, 0%). 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 #bcfe3f warm or cool?

Neutral — it scores 42 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #FEFA3F; nudged cooler, #76FF3E.

Which Tailwind color is closest to #bcfe3f?

The lime family — its 500 step is #84cc16, ΔE2000 11.9 away. That is a visible difference, so define #bcfe3f as a custom token rather than reaching for the built-in.

How do I use #bcfe3f in Tailwind CSS?

Inline it as an arbitrary value with bg-[#bcfe3f] or text-[#bcfe3f], 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 #bcfe3f with 50% opacity?

rgba(188, 254, 63, 0.5), or #bcfe3f80 in eight-digit hex. Over white that composites to #DEFF9F; over black, #5E7F20.

Is #bcfe3f a web-safe color?

No. The nearest web-safe colour is #CCFF33, ΔE2000 2.8 away. The palette only matters for legacy displays and some email clients now.

What does the color #bcfe3f mean?

As a green, it reads safe, growing, natural. Green means go, well, and grown. It carries finance, sustainability and health with almost no explanation needed. At this chroma the effect is amplified — it will dominate whatever sits beside it.

What gradient works with #bcfe3f?

The safest is same-hue elevation: linear-gradient(135deg, #D1FE7C, #bcfe3f 45%, #537F01). For more colour, a short hue run to #21FE36 keeps it rich without turning muddy.
