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 #ccf249

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 #5E7708
Safe as a 1px border on white
No — use #7FA10B

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.

What each alpha value actually composites to. The top row is #ccf249 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.

#ccf249, answered

What color is #ccf249?

#ccf249 is a balanced electric green, closest to Green Yellow (ΔE2000 6). It sits at 74° on the hue wheel with 87% saturation and 62% lightness, which reads as warm.

What is the RGB value of #ccf249?

rgb(204, 242, 73) — 204 red, 242 green and 73 blue out of 255, or 80% / 94.9% / 28.6% by channel.

What is #ccf249 in HSL and HSV?

hsl(74, 87%, 62%) and hsv(73, 70%, 95%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #ccf249 a light or a dark color?

It is a light color. Relative luminance is 0.7682 and perceived brightness is 85%, so black text on it reaches 16.36:1.

Should I use black or white text on #ccf249?

Black. It scores 16.36:1 against #ccf249, versus 1.28:1 for white — AAA at any size.

Is #ccf249 accessible on a white background?

#ccf249 on white scores 1.28:1, which fails WCAG AA at every size. Darken it to #658009 to reach 4.5:1, or #4B5E07 for 7:1.

What is the complementary color of #ccf249?

#6F49F2 sits directly opposite on the wheel. Softer options are the split-complements #4978F2 and #C449F2, which give the same contrast with far less vibration.

What colors go well with #ccf249?

For interface work: #F9FAF4 as the surface, #E3EDC0 for borders, #899B4B for secondary text, #454AF6 as an accent and #5E7708 for hover and pressed states. For a palette, the analogous pair #F2C449 and #78F249 stays calm, while #6F49F2 is the loudest partner.

What is #ccf249 in CMYK for printing?

cmyk(16%, 0%, 70%, 5%). 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 #ccf249 warm or cool?

Warm — it scores 36 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #F2DA49; nudged cooler, #8EF447.

Which Tailwind color is closest to #ccf249?

The lime family — its 500 step is #84cc16, ΔE2000 11.5 away. That is a visible difference, so define #ccf249 as a custom token rather than reaching for the built-in.

How do I use #ccf249 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#ccf249] or text-[#ccf249], 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 #ccf249 with 50% opacity?

rgba(204, 242, 73, 0.5), or #ccf24980 in eight-digit hex. Over white that composites to #E6F9A4; over black, #667925.

Is #ccf249 a web-safe color?

No. The nearest web-safe colour is #CCFF33, ΔE2000 3.3 away. The palette only matters for legacy displays and some email clients now.

What does the color #ccf249 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 #ccf249?
