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 #6ebfcd

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 #21565F
Safe as a 1px border on white
No — use #3DA0B1

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 #6ebfcd 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.

#6ebfcd, answered

What color is #6ebfcd?

#6ebfcd is a balanced vivid cyan, closest to Sky Blue (ΔE2000 7.5). It sits at 189° on the hue wheel with 49% saturation and 62% lightness, which reads as cool.

What is the RGB value of #6ebfcd?

rgb(110, 191, 205) — 110 red, 191 green and 205 blue out of 255, or 43.1% / 74.9% / 80.4% by channel.

What is #6ebfcd in HSL and HSV?

hsl(189, 49%, 62%) and hsv(189, 46%, 80%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #6ebfcd a light or a dark color?

It is a mid-tone. Relative luminance is 0.4498 and perceived brightness is 68%, so black text on it reaches 10.00:1.

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

Black. It scores 10.00:1 against #6ebfcd, versus 2.10:1 for white — AAA at any size.

Is #6ebfcd accessible on a white background?

#6ebfcd on white scores 2.10:1, which fails WCAG AA at every size. Darken it to #307E8C to reach 4.5:1, or #245F69 for 7:1.

What is the complementary color of #6ebfcd?

#CD7C6E sits directly opposite on the wheel. Softer options are the split-complements #CD6E90 and #CDAC6E, which give the same contrast with far less vibration.

What colors go well with #6ebfcd?

For interface work: #F4FAFA as the surface, #C2E4EA for borders, #4B8F9B for secondary text, #D16A75 as an accent and #21565F for hover and pressed states. For a palette, the analogous pair #6ECDAC and #6E90CD stays calm, while #CD7C6E is the loudest partner.

What is #6ebfcd in CMYK for printing?

cmyk(46%, 7%, 0%, 20%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #6ebfcd warm or cool?

Cool — it scores 91 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #6ECDB8; nudged cooler, #6CA7CF.

Which Tailwind color is closest to #6ebfcd?

The cyan family — its 500 step is #06b6d4, ΔE2000 6.7 away. That is a visible difference, so define #6ebfcd as a custom token rather than reaching for the built-in.

How do I use #6ebfcd in Tailwind CSS?

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

rgba(110, 191, 205, 0.5), or #6ebfcd80 in eight-digit hex. Over white that composites to #B7DFE6; over black, #376067.

Is #6ebfcd a web-safe color?

No. The nearest web-safe colour is #66CCCC, ΔE2000 6.9 away. The palette only matters for legacy displays and some email clients now.

What does the color #6ebfcd 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 #6ebfcd?

The safest is same-hue elevation: linear-gradient(135deg, #9CD3DD, #6ebfcd 45%, #21565F). For more colour, a short hue run to #5763C5 keeps it rich without turning muddy.
