How to use #d7ecf3

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 #1D5162
Safe as a 1px border on white
No — use #399EBF

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.

Transparency

What each alpha value actually composites to. The top row is #d7ecf3 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.

#d7ecf3, answered

What color is #d7ecf3?

#d7ecf3 is a pale vivid cyan, closest to Azure (ΔE2000 5.3). It sits at 195° on the hue wheel with 54% saturation and 90% lightness, which reads as cool.

What is the RGB value of #d7ecf3?

rgb(215, 236, 243) — 215 red, 236 green and 243 blue out of 255, or 84.3% / 92.5% / 95.3% by channel.

What is #d7ecf3 in HSL and HSV?

hsl(195, 54%, 90%) and hsv(195, 12%, 95%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #d7ecf3 a light or a dark color?

It is a light color. Relative luminance is 0.8091 and perceived brightness is 90%, so black text on it reaches 17.18:1.

Should I use black or white text on #d7ecf3?

Black. It scores 17.18:1 against #d7ecf3, versus 1.22:1 for white — AAA at any size.

Is #d7ecf3 accessible on a white background?

#d7ecf3 on white scores 1.22:1, which fails WCAG AA at every size. Darken it to #2E7E98 to reach 4.5:1, or #236075 for 7:1.

What is the complementary color of #d7ecf3?

#F3DED7 sits directly opposite on the wheel. Softer options are the split-complements #F3D7DE and #F3ECD7, which give the same contrast with far less vibration.

What colors go well with #d7ecf3?

For interface work: #F4F9FA as the surface, #C0E1EC for borders, #4B879B for secondary text, #A12B2B as an accent and #1D5162 for hover and pressed states. For a palette, the analogous pair #D7F3EC and #D7DEF3 stays calm, while #F3DED7 is the loudest partner.

What is #d7ecf3 in CMYK for printing?

cmyk(12%, 3%, 0%, 5%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #d7ecf3 warm or cool?

Cool — it scores 94 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #D7F3F0; nudged cooler, #D6E5F4.

Which Tailwind color is closest to #d7ecf3?

The cyan family — its 500 step is #06b6d4, ΔE2000 22.7 away. That is a visible difference, so define #d7ecf3 as a custom token rather than reaching for the built-in.

How do I use #d7ecf3 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#d7ecf3] or text-[#d7ecf3], 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 #d7ecf3 with 50% opacity?

rgba(215, 236, 243, 0.5), or #d7ecf380 in eight-digit hex. Over white that composites to #EBF6F9; over black, #6C767A.

Is #d7ecf3 a web-safe color?

No. The nearest web-safe colour is #CCFFFF, ΔE2000 9.7 away. The palette only matters for legacy displays and some email clients now.

What does the color #d7ecf3 mean?
