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 #5cbcdf

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 #15546B
Safe as a 1px border on white
No — use #28A0CC

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.

#5cbcdf, answered

What color is #5cbcdf?

#5cbcdf is a balanced vivid cyan, closest to Sky Blue (ΔE2000 5.9). It sits at 196° on the hue wheel with 67% saturation and 62% lightness, which reads as cool.

What is the RGB value of #5cbcdf?

rgb(92, 188, 223) — 92 red, 188 green and 223 blue out of 255, or 36.1% / 73.7% / 87.5% by channel.

What is #5cbcdf in HSL and HSV?

hsl(196, 67%, 62%) and hsv(196, 59%, 87%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #5cbcdf a light or a dark color?

It is a mid-tone. Relative luminance is 0.4357 and perceived brightness is 67%, so black text on it reaches 9.71:1.

Should I use black or white text on #5cbcdf?

Black. It scores 9.71:1 against #5cbcdf, versus 2.16:1 for white — AAA at any size.

Is #5cbcdf accessible on a white background?

#5cbcdf on white scores 2.16:1, which fails WCAG AA at every size. Darken it to #207FA1 to reach 4.5:1, or #18607B for 7:1.

What is the complementary color of #5cbcdf?

#DF7F5C sits directly opposite on the wheel. Softer options are the split-complements #DF5C7B and #DFC15C, which give the same contrast with far less vibration.

What colors go well with #5cbcdf?

For interface work: #F4F9FA as the surface, #C0E1ED for borders, #4B859B for secondary text, #E35B58 as an accent and #15546B for hover and pressed states. For a palette, the analogous pair #5CDFC1 and #5C7BDF stays calm, while #DF7F5C is the loudest partner.

What is #5cbcdf in CMYK for printing?

cmyk(59%, 16%, 0%, 13%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #5cbcdf warm or cool?

Cool — it scores 94 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #5CDFD2; nudged cooler, #5AA8E1.

Which Tailwind color is closest to #5cbcdf?

The cyan family — its 500 step is #06b6d4, ΔE2000 5.5 away. That is a visible difference, so define #5cbcdf as a custom token rather than reaching for the built-in.

How do I use #5cbcdf in Tailwind CSS?

Inline it as an arbitrary value with bg-[#5cbcdf] or text-[#5cbcdf], 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 #5cbcdf with 50% opacity?

rgba(92, 188, 223, 0.5), or #5cbcdf80 in eight-digit hex. Over white that composites to #AEDEEF; over black, #2E5E70.

Is #5cbcdf a web-safe color?

No. The nearest web-safe colour is #66CCCC, ΔE2000 13 away. The palette only matters for legacy displays and some email clients now.

What does the color #5cbcdf 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 #5cbcdf?

The safest is same-hue elevation: linear-gradient(135deg, #8FD1E9, #5cbcdf 45%, #15546B). For more colour, a short hue run to #4543DA keeps it rich without turning muddy.
