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 #7feaef

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 #0E6D71
Safe as a 1px border on white
No — use #15A5AB

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.

#7feaef, answered

What color is #7feaef?

#7feaef is a light electric cyan, closest to Pale Turquoise (ΔE2000 5.9). It sits at 183° on the hue wheel with 78% saturation and 72% lightness, which reads as cool.

What is the RGB value of #7feaef?

rgb(127, 234, 239) — 127 red, 234 green and 239 blue out of 255, or 49.8% / 91.8% / 93.7% by channel.

What is #7feaef in HSL and HSV?

hsl(183, 78%, 72%) and hsv(183, 47%, 94%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #7feaef a light or a dark color?

It is a light color. Relative luminance is 0.6959 and perceived brightness is 82%, so black text on it reaches 14.92:1.

Should I use black or white text on #7feaef?

Black. It scores 14.92:1 against #7feaef, versus 1.41:1 for white — AAA at any size.

Is #7feaef accessible on a white background?

#7feaef on white scores 1.41:1, which fails WCAG AA at every size. Darken it to #118287 to reach 4.5:1, or #0D6367 for 7:1.

What is the complementary color of #7feaef?

#EF847F sits directly opposite on the wheel. Softer options are the split-complements #EF7FB2 and #EFBC7F, which give the same contrast with far less vibration.

What colors go well with #7feaef?

For interface work: #F4FAFA as the surface, #C0EBED for borders, #4B979B for secondary text, #BA1234 as an accent and #0E6D71 for hover and pressed states. For a palette, the analogous pair #7FEFBC and #7FB2EF stays calm, while #EF847F is the loudest partner.

What is #7feaef in CMYK for printing?

cmyk(47%, 2%, 0%, 6%). 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 #7feaef warm or cool?

Cool — it scores 89 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #7FEFCB; nudged cooler, #7EC8F0.

Which Tailwind color is closest to #7feaef?

The cyan family — its 500 step is #06b6d4, ΔE2000 15.4 away. That is a visible difference, so define #7feaef as a custom token rather than reaching for the built-in.

How do I use #7feaef in Tailwind CSS?

Inline it as an arbitrary value with bg-[#7feaef] or text-[#7feaef], 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 #7feaef with 50% opacity?

rgba(127, 234, 239, 0.5), or #7feaef80 in eight-digit hex. Over white that composites to #BFF5F7; over black, #407578.

Is #7feaef a web-safe color?

No. The nearest web-safe colour is #66FFFF, ΔE2000 5.5 away. The palette only matters for legacy displays and some email clients now.

What does the color #7feaef 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 #7feaef?

The safest is same-hue elevation: linear-gradient(135deg, #B6F3F6, #7feaef 45%, #0E6D71). For more colour, a short hue run to #6480EC keeps it rich without turning muddy.
