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 #ceecf8

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 #105470
Safe as a 1px border on white
No — use #1E9FD2

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.

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

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 #ceecf8 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.

#ceecf8, answered

What color is #ceecf8?

#ceecf8 is a pale electric cyan, closest to Light Blue (ΔE2000 6). It sits at 197° on the hue wheel with 75% saturation and 89% lightness, which reads as cool.

What is the RGB value of #ceecf8?

rgb(206, 236, 248) — 206 red, 236 green and 248 blue out of 255, or 80.8% / 92.5% / 97.3% by channel.

What is #ceecf8 in HSL and HSV?

hsl(197, 75%, 89%) and hsv(197, 17%, 97%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #ceecf8 a light or a dark color?

It is a light color. Relative luminance is 0.7989 and perceived brightness is 90%, so black text on it reaches 16.98:1.

Should I use black or white text on #ceecf8?

Black. It scores 16.98:1 against #ceecf8, versus 1.24:1 for white — AAA at any size.

Is #ceecf8 accessible on a white background?

#ceecf8 on white scores 1.24:1, which fails WCAG AA at every size. Darken it to #187DA5 to reach 4.5:1, or #125E7D for 7:1.

What is the complementary color of #ceecf8?

#F8DACE sits directly opposite on the wheel. Softer options are the split-complements #F8CED7 and #F8EFCE, which give the same contrast with far less vibration.

What colors go well with #ceecf8?

For interface work: #F4F9FA as the surface, #C0E0ED for borders, #4B849B for secondary text, #B61A16 as an accent and #105470 for hover and pressed states. For a palette, the analogous pair #CEF8EF and #CED7F8 stays calm, while #F8DACE is the loudest partner.

What is #ceecf8 in CMYK for printing?

cmyk(17%, 5%, 0%, 3%). 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 #ceecf8 warm or cool?

Cool — it scores 95 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #CEF8F5; nudged cooler, #CDE4F9.

Which Tailwind color is closest to #ceecf8?

The cyan family — its 500 step is #06b6d4, ΔE2000 20.9 away. That is a visible difference, so define #ceecf8 as a custom token rather than reaching for the built-in.

How do I use #ceecf8 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#ceecf8] or text-[#ceecf8], 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 #ceecf8 with 50% opacity?

rgba(206, 236, 248, 0.5), or #ceecf880 in eight-digit hex. Over white that composites to #E7F6FC; over black, #67767C.

Is #ceecf8 a web-safe color?

No. The nearest web-safe colour is #CCFFFF, ΔE2000 8.9 away. The palette only matters for legacy displays and some email clients now.

What does the color #ceecf8 mean?

As a cyan, it reads clean, technical, fresh. Cyan reads as water, air and infrastructure: cool, hygienic, engineered. At this chroma the effect is amplified — it will dominate whatever sits beside it.

What gradient works with #ceecf8?
