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 #6fe2ce

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 #156A5B
Safe as a 1px border on white
No — use #21A68F

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.

Transparency

What each alpha value actually composites to. The top row is #6fe2ce 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.

#6fe2ce, answered

What color is #6fe2ce?

#6fe2ce is a light vivid cyan, closest to Turquoise (ΔE2000 3.4). It sits at 170° on the hue wheel with 67% saturation and 66% lightness, which reads as cool.

What is the RGB value of #6fe2ce?

rgb(111, 226, 206) — 111 red, 226 green and 206 blue out of 255, or 43.5% / 88.6% / 80.8% by channel.

What is #6fe2ce in HSL and HSV?

hsl(170, 67%, 66%) and hsv(170, 51%, 89%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #6fe2ce a light or a dark color?

It is a light color. Relative luminance is 0.6223 and perceived brightness is 77%, so black text on it reaches 13.45:1.

Should I use black or white text on #6fe2ce?

Black. It scores 13.45:1 against #6fe2ce, versus 1.56:1 for white — AAA at any size.

Is #6fe2ce accessible on a white background?

#6fe2ce on white scores 1.56:1, which fails WCAG AA at every size. Darken it to #1B8472 to reach 4.5:1, or #146254 for 7:1.

What is the complementary color of #6fe2ce?

#E26F83 sits directly opposite on the wheel. Softer options are the split-complements #E26FBC and #E2956F, which give the same contrast with far less vibration.

What colors go well with #6fe2ce?

For interface work: #F4FAF9 as the surface, #C0EDE5 for borders, #4B9B8D for secondary text, #AD1F5B as an accent and #156A5B for hover and pressed states. For a palette, the analogous pair #6FE295 and #6FBCE2 stays calm, while #E26F83 is the loudest partner.

What is #6fe2ce in CMYK for printing?

cmyk(51%, 0%, 9%, 11%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #6fe2ce warm or cool?

Cool — it scores 83 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #6FE2A4; nudged cooler, #6DCDE4.

Which Tailwind color is closest to #6fe2ce?

The teal family — its 500 step is #14b8a6, ΔE2000 11.5 away. That is a visible difference, so define #6fe2ce as a custom token rather than reaching for the built-in.

How do I use #6fe2ce in Tailwind CSS?

Inline it as an arbitrary value with bg-[#6fe2ce] or text-[#6fe2ce], 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 #6fe2ce with 50% opacity?

rgba(111, 226, 206, 0.5), or #6fe2ce80 in eight-digit hex. Over white that composites to #B7F1E7; over black, #387167.

Is #6fe2ce a web-safe color?

No. The nearest web-safe colour is #66CCCC, ΔE2000 8.6 away. The palette only matters for legacy displays and some email clients now.

What does the color #6fe2ce 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 #6fe2ce?

The safest is same-hue elevation: linear-gradient(135deg, #A2ECDF, #6fe2ce 45%, #156A5B). For more colour, a short hue run to #568FDD keeps it rich without turning muddy.
