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 #72c0fd

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
  • 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 #02477E
Safe as a 1px border on white
No — use #1898FC

Meaning and mood

What a colour in this family tends to signal, and how this particular chroma and lightness change the reading.

trustedcalmcompetentcorporate

The default of institutions for a reason: blue is read as stable and safe across nearly every culture that has been surveyed.

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

It is also the most crowded hue on the web. Distinctiveness has to come from your other choices.

#72c0fd, answered

What color is #72c0fd?

#72c0fd is a light electric blue, closest to Light Sky Blue (ΔE2000 4.8). It sits at 206° on the hue wheel with 97% saturation and 72% lightness, which reads as cool.

What is the RGB value of #72c0fd?

rgb(114, 192, 253) — 114 red, 192 green and 253 blue out of 255, or 44.7% / 75.3% / 99.2% by channel.

What is #72c0fd in HSL and HSV?

hsl(206, 97%, 72%) and hsv(206, 55%, 99%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #72c0fd a light or a dark color?

It is a mid-tone. Relative luminance is 0.4837 and perceived brightness is 71%, so black text on it reaches 10.67:1.

Should I use black or white text on #72c0fd?

Black. It scores 10.67:1 against #72c0fd, versus 1.97:1 for white — AAA at any size.

Is #72c0fd accessible on a white background?

#72c0fd on white scores 1.97:1, which fails WCAG AA at every size. Darken it to #0378D3 to reach 4.5:1, or #02599C for 7:1.

What is the complementary color of #72c0fd?

#FDAF72 sits directly opposite on the wheel. Softer options are the split-complements #FD727B and #FDF472, which give the same contrast with far less vibration.

What colors go well with #72c0fd?

For interface work: #F4F8FA as the surface, #C0D9ED for borders, #4B789B for secondary text, #CC2600 as an accent and #02477E for hover and pressed states. For a palette, the analogous pair #72FDF4 and #727BFD stays calm, while #FDAF72 is the loudest partner.

What is #72c0fd in CMYK for printing?

cmyk(55%, 24%, 0%, 1%). 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 #72c0fd warm or cool?

Cool — it scores 98 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #728DFD; nudged cooler, #57ACFE.

Which Tailwind color is closest to #72c0fd?

The sky family — its 500 step is #0ea5e9, ΔE2000 9.2 away. That is a visible difference, so define #72c0fd as a custom token rather than reaching for the built-in.

How do I use #72c0fd in Tailwind CSS?

Inline it as an arbitrary value with bg-[#72c0fd] or text-[#72c0fd], 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 #72c0fd with 50% opacity?

rgba(114, 192, 253, 0.5), or #72c0fd80 in eight-digit hex. Over white that composites to #B9E0FE; over black, #39607F.

Is #72c0fd a web-safe color?

No. The nearest web-safe colour is #66CCFF, ΔE2000 5.4 away. The palette only matters for legacy displays and some email clients now.

What does the color #72c0fd mean?
