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 #cbed39

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 #61750B
Safe as a 1px border on white
No — use #829D0E

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 #cbed39 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.

#cbed39, answered

What color is #cbed39?

#cbed39 is a balanced electric green, closest to Green Yellow (ΔE2000 7). It sits at 71° on the hue wheel with 83% saturation and 58% lightness, which reads as warm.

What is the RGB value of #cbed39?

rgb(203, 237, 57) — 203 red, 237 green and 57 blue out of 255, or 79.6% / 92.9% / 22.4% by channel.

What is #cbed39 in HSL and HSV?

hsl(71, 83%, 58%) and hsv(71, 76%, 93%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #cbed39 a light or a dark color?

It is a light color. Relative luminance is 0.7356 and perceived brightness is 84%, so black text on it reaches 15.71:1.

Should I use black or white text on #cbed39?

Black. It scores 15.71:1 against #cbed39, versus 1.34:1 for white — AAA at any size.

Is #cbed39 accessible on a white background?

#cbed39 on white scores 1.34:1, which fails WCAG AA at every size. Darken it to #677C0B to reach 4.5:1, or #4C5C08 for 7:1.

What is the complementary color of #cbed39?

#5B39ED sits directly opposite on the wheel. Softer options are the split-complements #3971ED and #B539ED, which give the same contrast with far less vibration.

What colors go well with #cbed39?

For interface work: #F9FAF4 as the surface, #E4EDC0 for borders, #8C9B4B for secondary text, #3440F1 as an accent and #61750B for hover and pressed states. For a palette, the analogous pair #EDB539 and #71ED39 stays calm, while #5B39ED is the loudest partner.

What is #cbed39 in CMYK for printing?

cmyk(14%, 0%, 76%, 7%). 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 #cbed39 warm or cool?

Warm — it scores 34 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #EDCD39; nudged cooler, #89EF37.

Which Tailwind color is closest to #cbed39?

The lime family — its 500 step is #84cc16, ΔE2000 11.3 away. That is a visible difference, so define #cbed39 as a custom token rather than reaching for the built-in.

How do I use #cbed39 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#cbed39] or text-[#cbed39], 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 #cbed39 with 50% opacity?

rgba(203, 237, 57, 0.5), or #cbed3980 in eight-digit hex. Over white that composites to #E5F69C; over black, #66771D.

Is #cbed39 a web-safe color?

No. The nearest web-safe colour is #CCFF33, ΔE2000 4.1 away. The palette only matters for legacy displays and some email clients now.

What does the color #cbed39 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 #cbed39?
