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 #8feccf

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 #126D51
Safe as a 1px border on white
No — use #1CA77C

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 lightness keeps it airy and approachable.

Worth knowing

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

#8feccf, answered

What color is #8feccf?

#8feccf is a light vivid cyan, closest to Aqua Marine (ΔE2000 5.4). It sits at 161° on the hue wheel with 71% saturation and 74% lightness, which reads as cool.

What is the RGB value of #8feccf?

rgb(143, 236, 207) — 143 red, 236 green and 207 blue out of 255, or 56.1% / 92.5% / 81.2% by channel.

What is #8feccf in HSL and HSV?

hsl(161, 71%, 74%) and hsv(161, 39%, 93%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #8feccf a light or a dark color?

It is a light color. Relative luminance is 0.7034 and perceived brightness is 82%, so black text on it reaches 15.07:1.

Should I use black or white text on #8feccf?

Black. It scores 15.07:1 against #8feccf, versus 1.39:1 for white — AAA at any size.

Is #8feccf accessible on a white background?

#8feccf on white scores 1.39:1, which fails WCAG AA at every size. Darken it to #168462 to reach 4.5:1, or #106148 for 7:1.

What is the complementary color of #8feccf?

#EC8FAC sits directly opposite on the wheel. Softer options are the split-complements #EC8FDA and #ECA08F, which give the same contrast with far less vibration.

What colors go well with #8feccf?

For interface work: #F4FAF9 as the surface, #C0EDDF for borders, #4B9B82 for secondary text, #B31970 as an accent and #126D51 for hover and pressed states. For a palette, the analogous pair #8FECA0 and #8FDAEC stays calm, while #EC8FAC is the loudest partner.

What is #8feccf in CMYK for printing?

cmyk(39%, 0%, 12%, 8%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #8feccf warm or cool?

Cool — it scores 80 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #8FECAD; nudged cooler, #8EE8ED.

Which Tailwind color is closest to #8feccf?

The teal family — its 500 step is #14b8a6, ΔE2000 15.1 away. That is a visible difference, so define #8feccf as a custom token rather than reaching for the built-in.

How do I use #8feccf in Tailwind CSS?

Inline it as an arbitrary value with bg-[#8feccf] or text-[#8feccf], 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 #8feccf with 50% opacity?

rgba(143, 236, 207, 0.5), or #8feccf80 in eight-digit hex. Over white that composites to #C7F6E7; over black, #487668.

Is #8feccf a web-safe color?

No. The nearest web-safe colour is #99FFCC, ΔE2000 6.6 away. The palette only matters for legacy displays and some email clients now.

What does the color #8feccf 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 #8feccf?

The safest is same-hue elevation: linear-gradient(135deg, #C3F5E5, #8feccf 45%, #126D51). For more colour, a short hue run to #75B5E8 keeps it rich without turning muddy.
