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 #cef2fa

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 #0C6174
Safe as a 1px border on white
No — use #14A0C0

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.

#cef2fa, answered

What color is #cef2fa?

#cef2fa is a pale electric cyan, closest to Light Cyan (ΔE2000 4.4). It sits at 191° on the hue wheel with 82% saturation and 89% lightness, which reads as cool.

What is the RGB value of #cef2fa?

rgb(206, 242, 250) — 206 red, 242 green and 250 blue out of 255, or 80.8% / 94.9% / 98% by channel.

What is #cef2fa in HSL and HSV?

hsl(191, 82%, 89%) and hsv(191, 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 #cef2fa a light or a dark color?

It is a light color. Relative luminance is 0.8353 and perceived brightness is 91%, so black text on it reaches 17.71:1.

Should I use black or white text on #cef2fa?

Black. It scores 17.71:1 against #cef2fa, versus 1.19:1 for white — AAA at any size.

Is #cef2fa accessible on a white background?

#cef2fa on white scores 1.19:1, which fails WCAG AA at every size. Darken it to #10819B to reach 4.5:1, or #0C5F71 for 7:1.

What is the complementary color of #cef2fa?

#FAD6CE sits directly opposite on the wheel. Softer options are the split-complements #FACEDC and #FAECCE, which give the same contrast with far less vibration.

What colors go well with #cef2fa?

For interface work: #F4F9FA as the surface, #C0E4ED for borders, #4B8C9B for secondary text, #BD0F1A as an accent and #0C6174 for hover and pressed states. For a palette, the analogous pair #CEFAEC and #CEDCFA stays calm, while #FAD6CE is the loudest partner.

What is #cef2fa in CMYK for printing?

cmyk(18%, 3%, 0%, 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 #cef2fa warm or cool?

Cool — it scores 92 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #CEFAF2; nudged cooler, #CDE6FB.

Which Tailwind color is closest to #cef2fa?

The cyan family — its 500 step is #06b6d4, ΔE2000 21.1 away. That is a visible difference, so define #cef2fa as a custom token rather than reaching for the built-in.

How do I use #cef2fa in Tailwind CSS?

Inline it as an arbitrary value with bg-[#cef2fa] or text-[#cef2fa], 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 #cef2fa with 50% opacity?

rgba(206, 242, 250, 0.5), or #cef2fa80 in eight-digit hex. Over white that composites to #E7F9FD; over black, #67797D.

Is #cef2fa a web-safe color?

No. The nearest web-safe colour is #CCFFFF, ΔE2000 5.9 away. The palette only matters for legacy displays and some email clients now.

What does the color #cef2fa 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 #cef2fa?

The safest is same-hue elevation: linear-gradient(135deg, #ECFAFD, #cef2fa 45%, #0C6174). For more colour, a short hue run to #B2B7F7 keeps it rich without turning muddy.
