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 #6cecec

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 #0F7171
Safe as a 1px border on white
No — use #15A5A5

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.

Transparency

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

#6cecec, answered

What color is #6cecec?

#6cecec is a light electric cyan, closest to Cyan (ΔE2000 5.3). It sits at 180° on the hue wheel with 77% saturation and 68% lightness, which reads as cool.

What is the RGB value of #6cecec?

rgb(108, 236, 236) — 108 red, 236 green and 236 blue out of 255, or 42.4% / 92.5% / 92.5% by channel.

What is #6cecec in HSL and HSV?

hsl(180, 77%, 68%) and hsv(180, 54%, 93%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #6cecec a light or a dark color?

It is a light color. Relative luminance is 0.6924 and perceived brightness is 81%, so black text on it reaches 14.85:1.

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

Black. It scores 14.85:1 against #6cecec, versus 1.41:1 for white — AAA at any size.

Is #6cecec accessible on a white background?

#6cecec on white scores 1.41:1, which fails WCAG AA at every size. Darken it to #118181 to reach 4.5:1, or #0D6161 for 7:1.

What is the complementary color of #6cecec?

#EC6C6C sits directly opposite on the wheel. Softer options are the split-complements #EC6CAC and #ECAC6C, which give the same contrast with far less vibration.

What colors go well with #6cecec?

For interface work: #F4FAFA as the surface, #C0EDED for borders, #4B9B9B for secondary text, #B8143D as an accent and #0F7171 for hover and pressed states. For a palette, the analogous pair #6CECAC and #6CACEC stays calm, while #EC6C6C is the loudest partner.

What is #6cecec in CMYK for printing?

cmyk(54%, 0%, 0%, 8%). 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 #6cecec warm or cool?

Cool — it scores 88 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #6CECBD; nudged cooler, #6BC4EE.

Which Tailwind color is closest to #6cecec?

The teal family — its 500 step is #14b8a6, ΔE2000 15.3 away. That is a visible difference, so define #6cecec as a custom token rather than reaching for the built-in.

How do I use #6cecec in Tailwind CSS?

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

rgba(108, 236, 236, 0.5), or #6cecec80 in eight-digit hex. Over white that composites to #B6F6F6; over black, #367676.

Is #6cecec a web-safe color?

No. The nearest web-safe colour is #66FFFF, ΔE2000 4 away. The palette only matters for legacy displays and some email clients now.

What does the color #6cecec 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 #6cecec?

The safest is same-hue elevation: linear-gradient(135deg, #A2F3F3, #6cecec 45%, #0F7171). For more colour, a short hue run to #5177E9 keeps it rich without turning muddy.
