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 #6cdbc8

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 #196659
Safe as a 1px border on white
No — use #28A48F

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.

Transparency

What each alpha value actually composites to. The top row is #6cdbc8 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.

#6cdbc8, answered

What color is #6cdbc8?

#6cdbc8 is a balanced vivid cyan, closest to Turquoise (ΔE2000 3.5). It sits at 170° on the hue wheel with 61% saturation and 64% lightness, which reads as cool.

What is the RGB value of #6cdbc8?

rgb(108, 219, 200) — 108 red, 219 green and 200 blue out of 255, or 42.4% / 85.9% / 78.4% by channel.

What is #6cdbc8 in HSL and HSV?

hsl(170, 61%, 64%) and hsv(170, 51%, 86%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #6cdbc8 a light or a dark color?

It is a light color. Relative luminance is 0.5802 and perceived brightness is 75%, so black text on it reaches 12.60:1.

Should I use black or white text on #6cdbc8?

Black. It scores 12.60:1 against #6cdbc8, versus 1.67:1 for white — AAA at any size.

Is #6cdbc8 accessible on a white background?

#6cdbc8 on white scores 1.67:1, which fails WCAG AA at every size. Darken it to #208472 to reach 4.5:1, or #186356 for 7:1.

What is the complementary color of #6cdbc8?

#DB6C7F sits directly opposite on the wheel. Softer options are the split-complements #DB6CB7 and #DB906C, which give the same contrast with far less vibration.

What colors go well with #6cdbc8?

For interface work: #F4FAF9 as the surface, #C0EDE5 for borders, #4B9B8D for secondary text, #DF689A as an accent and #196659 for hover and pressed states. For a palette, the analogous pair #6CDB90 and #6CB7DB stays calm, while #DB6C7F is the loudest partner.

What is #6cdbc8 in CMYK for printing?

cmyk(51%, 0%, 9%, 14%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #6cdbc8 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 #6CDB9F; nudged cooler, #6AC6DD.

Which Tailwind color is closest to #6cdbc8?

The teal family — its 500 step is #14b8a6, ΔE2000 10.1 away. That is a visible difference, so define #6cdbc8 as a custom token rather than reaching for the built-in.

How do I use #6cdbc8 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#6cdbc8] or text-[#6cdbc8], 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 #6cdbc8 with 50% opacity?

rgba(108, 219, 200, 0.5), or #6cdbc880 in eight-digit hex. Over white that composites to #B6EDE4; over black, #366E64.

Is #6cdbc8 a web-safe color?

No. The nearest web-safe colour is #66CCCC, ΔE2000 7.5 away. The palette only matters for legacy displays and some email clients now.

What does the color #6cdbc8 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 #6cdbc8?

The safest is same-hue elevation: linear-gradient(135deg, #9DE7DA, #6cdbc8 45%, #196659). For more colour, a short hue run to #538AD5 keeps it rich without turning muddy.
