How to use #c9e9da

Derived from its contrast, chroma and lightness — not from taste.

Works well for
  • Text and icons on dark surfaces
  • Charts, tags and secondary surfaces
  • Card and section backgrounds
  • Brand accents, badges and data highlights
Use with care
  • Text of any size on white — fails WCAG AA
  • 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 #255B41
Safe as a 1px border on white
No — use #43A376

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.

The muted chroma softens the association — it reads considered rather than loud, which suits long-form and data-heavy screens. 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 #c9e9da 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.

#c9e9da, answered

What color is #c9e9da?

#c9e9da is a pale soft green, closest to Honey Dew (ΔE2000 7.6). It sits at 152° on the hue wheel with 42% saturation and 85% lightness, which reads as cool.

What is the RGB value of #c9e9da?

rgb(201, 233, 218) — 201 red, 233 green and 218 blue out of 255, or 78.8% / 91.4% / 85.5% by channel.

What is #c9e9da in HSL and HSV?

hsl(152, 42%, 85%) and hsv(152, 14%, 91%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #c9e9da a light or a dark color?

It is a light color. Relative luminance is 0.7576 and perceived brightness is 87%, so black text on it reaches 16.15:1.

Should I use black or white text on #c9e9da?

Black. It scores 16.15:1 against #c9e9da, versus 1.30:1 for white — AAA at any size.

Is #c9e9da accessible on a white background?

#c9e9da on white scores 1.30:1, which fails WCAG AA at every size. Darken it to #35835F to reach 4.5:1, or #286247 for 7:1.

What is the complementary color of #c9e9da?

#E9C9D8 sits directly opposite on the wheel. Softer options are the split-complements #E9C9E8 and #E9CAC9, which give the same contrast with far less vibration.

What colors go well with #c9e9da?

For interface work: #F4FAF8 as the surface, #C5E7D7 for borders, #4B9B75 for secondary text, #96367B as an accent and #255B41 for hover and pressed states. For a palette, the analogous pair #C9E9CA and #C9E8E9 stays calm, while #E9C9D8 is the loudest partner.

What is #c9e9da in CMYK for printing?

cmyk(14%, 0%, 6%, 9%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #c9e9da warm or cool?

Cool — it scores 76 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #C9E9CE; nudged cooler, #C8EAE6.

Which Tailwind color is closest to #c9e9da?

The teal family — its 500 step is #14b8a6, ΔE2000 21 away. That is a visible difference, so define #c9e9da as a custom token rather than reaching for the built-in.

How do I use #c9e9da in Tailwind CSS?

Inline it as an arbitrary value with bg-[#c9e9da] or text-[#c9e9da], 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 #c9e9da with 50% opacity?

rgba(201, 233, 218, 0.5), or #c9e9da80 in eight-digit hex. Over white that composites to #E4F4ED; over black, #65756D.

Is #c9e9da a web-safe color?

No. The nearest web-safe colour is #CCFFCC, ΔE2000 11 away. The palette only matters for legacy displays and some email clients now.

What does the color #c9e9da mean?
