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 #6adfcc

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
  • Brand accents, badges and data highlights
  • Chart series and data categories
Use with care
  • Text of any size on white — fails WCAG AA
  • Full-page backgrounds — tiring over long sessions
  • 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 #17695C
Safe as a 1px border on white
No — use #24A691

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 mid lightness keeps it versatile in both themes.

Worth knowing

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

#6adfcc, answered

What color is #6adfcc?

#6adfcc is a balanced vivid cyan, closest to Turquoise (ΔE2000 3). It sits at 170° on the hue wheel with 65% saturation and 65% lightness, which reads as cool.

What is the RGB value of #6adfcc?

rgb(106, 223, 204) — 106 red, 223 green and 204 blue out of 255, or 41.6% / 87.5% / 80% by channel.

What is #6adfcc in HSL and HSV?

hsl(170, 65%, 65%) and hsv(170, 52%, 87%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #6adfcc a light or a dark color?

It is a light color. Relative luminance is 0.6020 and perceived brightness is 76%, so black text on it reaches 13.04:1.

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

Black. It scores 13.04:1 against #6adfcc, versus 1.61:1 for white — AAA at any size.

Is #6adfcc accessible on a white background?

#6adfcc on white scores 1.61:1, which fails WCAG AA at every size. Darken it to #1C8473 to reach 4.5:1, or #156356 for 7:1.

What is the complementary color of #6adfcc?

#DF6A7D sits directly opposite on the wheel. Softer options are the split-complements #DF6AB7 and #DF926A, which give the same contrast with far less vibration.

What colors go well with #6adfcc?

For interface work: #F4FAF9 as the surface, #C0EDE5 for borders, #4B9B8E for secondary text, #E3669A as an accent and #17695C for hover and pressed states. For a palette, the analogous pair #6ADF92 and #6AB7DF stays calm, while #DF6A7D is the loudest partner.

What is #6adfcc in CMYK for printing?

cmyk(53%, 0%, 9%, 13%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #6adfcc 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 #6ADFA1; nudged cooler, #68C8E1.

Which Tailwind color is closest to #6adfcc?

The teal family — its 500 step is #14b8a6, ΔE2000 10.8 away. That is a visible difference, so define #6adfcc as a custom token rather than reaching for the built-in.

How do I use #6adfcc in Tailwind CSS?

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

rgba(106, 223, 204, 0.5), or #6adfcc80 in eight-digit hex. Over white that composites to #B5EFE6; over black, #357066.

Is #6adfcc a web-safe color?

No. The nearest web-safe colour is #66CCCC, ΔE2000 7.9 away. The palette only matters for legacy displays and some email clients now.

What does the color #6adfcc 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 #6adfcc?

The safest is same-hue elevation: linear-gradient(135deg, #9CEADD, #6adfcc 45%, #17695C). For more colour, a short hue run to #5189DA keeps it rich without turning muddy.
