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 #ecf9cb

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 #56720D
Safe as a 1px border on white
No — use #779E12

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 high lightness makes it recede — a surface colour rather than a statement.

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 #ecf9cb 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.

#ecf9cb, answered

What color is #ecf9cb?

#ecf9cb is a pale electric green, closest to Light Goldenrod Yellow (ΔE2000 4.5). It sits at 77° on the hue wheel with 79% saturation and 89% lightness, which reads as warm.

What is the RGB value of #ecf9cb?

rgb(236, 249, 203) — 236 red, 249 green and 203 blue out of 255, or 92.5% / 97.6% / 79.6% by channel.

What is #ecf9cb in HSL and HSV?

hsl(77, 79%, 89%) and hsv(77, 18%, 98%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #ecf9cb a light or a dark color?

It is a light color. Relative luminance is 0.8990 and perceived brightness is 94%, so black text on it reaches 18.98:1.

Should I use black or white text on #ecf9cb?

Black. It scores 18.98:1 against #ecf9cb, versus 1.11:1 for white — AAA at any size.

Is #ecf9cb accessible on a white background?

#ecf9cb on white scores 1.11:1, which fails WCAG AA at every size. Darken it to #5F7E0F to reach 4.5:1, or #475E0B for 7:1.

What is the complementary color of #ecf9cb?

#D8CBF9 sits directly opposite on the wheel. Softer options are the split-complements #CBD5F9 and #EFCBF9, which give the same contrast with far less vibration.

What colors go well with #ecf9cb?

For interface work: #F9FAF4 as the surface, #E0EDC0 for borders, #849B4B for secondary text, #1512BA as an accent and #56720D for hover and pressed states. For a palette, the analogous pair #F9EFCB and #D5F9CB stays calm, while #D8CBF9 is the loudest partner.

What is #ecf9cb in CMYK for printing?

cmyk(5%, 0%, 19%, 2%). 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 #ecf9cb warm or cool?

Warm — it scores 39 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #F9F5CB; nudged cooler, #DBFACA.

Which Tailwind color is closest to #ecf9cb?

The lime family — its 500 step is #84cc16, ΔE2000 22.5 away. That is a visible difference, so define #ecf9cb as a custom token rather than reaching for the built-in.

How do I use #ecf9cb in Tailwind CSS?

Inline it as an arbitrary value with bg-[#ecf9cb] or text-[#ecf9cb], 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 #ecf9cb with 50% opacity?

rgba(236, 249, 203, 0.5), or #ecf9cb80 in eight-digit hex. Over white that composites to #F6FCE5; over black, #767D66.

Is #ecf9cb a web-safe color?

No. The nearest web-safe colour is #FFFFCC, ΔE2000 4.5 away. The palette only matters for legacy displays and some email clients now.

What does the color #ecf9cb 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 #ecf9cb?
