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

How to use #cdf09a

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
  • Card and section backgrounds
  • 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
  • White text placed on it
  • 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 #496F11
Safe as a 1px border on white
No — use #69A118

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.

This is a confident chroma: strong enough to lead a brand, restrained enough to live in an interface all day. The lightness keeps it airy and approachable.

Worth knowing

Red/green pairs are the most common colour-blindness failure — never let the two carry meaning alone.

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.

#cdf09a, answered

What color is #cdf09a?

#cdf09a is a light vivid green, closest to Light Green (ΔE2000 9.2). It sits at 84° on the hue wheel with 74% saturation and 77% lightness, which reads as neutral.

What is the RGB value of #cdf09a?

rgb(205, 240, 154) — 205 red, 240 green and 154 blue out of 255, or 80.4% / 94.1% / 60.4% by channel.

What is #cdf09a in HSL and HSV?

hsl(84, 74%, 77%) and hsv(84, 36%, 94%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #cdf09a a light or a dark color?

It is a light color. Relative luminance is 0.7763 and perceived brightness is 87%, so black text on it reaches 16.53:1.

Should I use black or white text on #cdf09a?

Black. It scores 16.53:1 against #cdf09a, versus 1.27:1 for white — AAA at any size.

Is #cdf09a accessible on a white background?

#cdf09a on white scores 1.27:1, which fails WCAG AA at every size. Darken it to #558213 to reach 4.5:1, or #3E5F0E for 7:1.

What is the complementary color of #cdf09a?

#BD9AF0 sits directly opposite on the wheel. Softer options are the split-complements #9AA2F0 and #E89AF0, which give the same contrast with far less vibration.

What colors go well with #cdf09a?

For interface work: #F8FAF4 as the surface, #DAEDC0 for borders, #7A9B4B for secondary text, #2F17B5 as an accent and #496F11 for hover and pressed states. For a palette, the analogous pair #F0E89A and #A2F09A stays calm, while #BD9AF0 is the loudest partner.

What is #cdf09a in CMYK for printing?

cmyk(15%, 0%, 36%, 6%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #cdf09a warm or cool?

Neutral — it scores 45 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #EDF09A; nudged cooler, #ADF199.

Which Tailwind color is closest to #cdf09a?

The lime family — its 500 step is #84cc16, ΔE2000 14.6 away. That is a visible difference, so define #cdf09a as a custom token rather than reaching for the built-in.

How do I use #cdf09a in Tailwind CSS?

Inline it as an arbitrary value with bg-[#cdf09a] or text-[#cdf09a], 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 #cdf09a with 50% opacity?

rgba(205, 240, 154, 0.5), or #cdf09a80 in eight-digit hex. Over white that composites to #E6F8CD; over black, #67784D.

Is #cdf09a a web-safe color?

No. The nearest web-safe colour is #CCFF99, ΔE2000 4 away. The palette only matters for legacy displays and some email clients now.

What does the color #cdf09a 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 #cdf09a?
