How to use #85cfee

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 #105370
Safe as a 1px border on white
No — use #1E9FD5

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 lightness keeps it airy and approachable.

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 #85cfee 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.

#85cfee, answered

What color is #85cfee?

#85cfee is a light electric cyan — the CSS keyword Sky Blue. It sits at 198° on the hue wheel with 76% saturation and 73% lightness, which reads as cool.

What is the RGB value of #85cfee?

rgb(133, 207, 238) — 133 red, 207 green and 238 blue out of 255, or 52.2% / 81.2% / 93.3% by channel.

What is #85cfee in HSL and HSV?

hsl(198, 76%, 73%) and hsv(198, 44%, 93%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #85cfee a light or a dark color?

It is a light color. Relative luminance is 0.5579 and perceived brightness is 75%, so black text on it reaches 12.16:1.

Should I use black or white text on #85cfee?

Black. It scores 12.16:1 against #85cfee, versus 1.73:1 for white — AAA at any size.

Is #85cfee accessible on a white background?

#85cfee on white scores 1.73:1, which fails WCAG AA at every size. Darken it to #187EA9 to reach 4.5:1, or #115D7C for 7:1.

What is the complementary color of #85cfee?

#EEA485 sits directly opposite on the wheel. Softer options are the split-complements #EE859A and #EED885, which give the same contrast with far less vibration.

What colors go well with #85cfee?

For interface work: #F4F9FA as the surface, #C0DFED for borders, #4B839B for secondary text, #B71C15 as an accent and #105370 for hover and pressed states. For a palette, the analogous pair #85EED8 and #859AEE stays calm, while #EEA485 is the loudest partner.

What is #85cfee in CMYK for printing?

cmyk(44%, 13%, 0%, 7%). 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 #85cfee 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 #85EEE6; nudged cooler, #83BFEF.

Which Tailwind color is closest to #85cfee?

The cyan family — its 500 step is #06b6d4, ΔE2000 10.4 away. That is a visible difference, so define #85cfee as a custom token rather than reaching for the built-in.

How do I use #85cfee in Tailwind CSS?

Inline it as an arbitrary value with bg-[#85cfee] or text-[#85cfee], 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 #85cfee with 50% opacity?

rgba(133, 207, 238, 0.5), or #85cfee80 in eight-digit hex. Over white that composites to #C2E7F7; over black, #436877.

Is #85cfee a web-safe color?

No. The nearest web-safe colour is #99CCFF, ΔE2000 8.3 away. The palette only matters for legacy displays and some email clients now.

What does the color #85cfee 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 #85cfee?
