How to use #d3f7f3

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
  • Thin strokes and 1px borders — they disappear on light UI
  • 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 #146C62
Safe as a 1px border on white
No — use #1EA394

Meaning and mood

What a colour in this family tends to signal, and how this particular chroma and lightness change the reading.

cleantechnicalfreshclinical

Cyan reads as water, air and infrastructure: cool, hygienic, engineered.

This is a confident chroma: strong enough to lead a brand, restrained enough to live in an interface all day. The high lightness makes it recede — a surface colour rather than a statement.

Worth knowing

At high lightness it disappears into white surfaces and thin strokes vanish entirely.

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.

#d3f7f3, answered

What color is #d3f7f3?

#d3f7f3 is a pale vivid cyan, closest to Light Cyan (ΔE2000 3.1). It sits at 173° on the hue wheel with 69% saturation and 90% lightness, which reads as cool.

What is the RGB value of #d3f7f3?

rgb(211, 247, 243) — 211 red, 247 green and 243 blue out of 255, or 82.7% / 96.9% / 95.3% by channel.

What is #d3f7f3 in HSL and HSV?

hsl(173, 69%, 90%) and hsv(173, 15%, 97%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #d3f7f3 a light or a dark color?

It is a light color. Relative luminance is 0.8684 and perceived brightness is 93%, so black text on it reaches 18.37:1.

Should I use black or white text on #d3f7f3?

Black. It scores 18.37:1 against #d3f7f3, versus 1.14:1 for white — AAA at any size.

Is #d3f7f3 accessible on a white background?

#d3f7f3 on white scores 1.14:1, which fails WCAG AA at every size. Darken it to #188579 to reach 4.5:1, or #126259 for 7:1.

What is the complementary color of #d3f7f3?

#F7D3D7 sits directly opposite on the wheel. Softer options are the split-complements #F7D3E9 and #F7E1D3, which give the same contrast with far less vibration.

What colors go well with #d3f7f3?

For interface work: #F4FAFA as the surface, #C0EDE8 for borders, #4B9B92 for secondary text, #B11B52 as an accent and #146C62 for hover and pressed states. For a palette, the analogous pair #D3F7E1 and #D3E9F7 stays calm, while #F7D3D7 is the loudest partner.

What is #d3f7f3 in CMYK for printing?

cmyk(15%, 0%, 2%, 3%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #d3f7f3 warm or cool?

Cool — it scores 85 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #D3F7E6; nudged cooler, #D2EEF8.

Which Tailwind color is closest to #d3f7f3?

The teal family — its 500 step is #14b8a6, ΔE2000 23.3 away. That is a visible difference, so define #d3f7f3 as a custom token rather than reaching for the built-in.

How do I use #d3f7f3 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#d3f7f3] or text-[#d3f7f3], 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 #d3f7f3 with 50% opacity?
