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 #7cbcf2

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 #0C4474
Safe as a 1px border on white
No — use #3798EB

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.

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.

#7cbcf2, answered

What color is #7cbcf2?

#7cbcf2 is a light electric blue, closest to Light Sky Blue (ΔE2000 5.3). It sits at 208° on the hue wheel with 82% saturation and 72% lightness, which reads as cool.

What is the RGB value of #7cbcf2?

rgb(124, 188, 242) — 124 red, 188 green and 242 blue out of 255, or 48.6% / 73.7% / 94.9% by channel.

What is #7cbcf2 in HSL and HSV?

hsl(208, 82%, 72%) and hsv(207, 49%, 95%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #7cbcf2 a light or a dark color?

It is a mid-tone. Relative luminance is 0.4666 and perceived brightness is 70%, so black text on it reaches 10.33:1.

Should I use black or white text on #7cbcf2?

Black. It scores 10.33:1 against #7cbcf2, versus 2.03:1 for white — AAA at any size.

Is #7cbcf2 accessible on a white background?

#7cbcf2 on white scores 2.03:1, which fails WCAG AA at every size. Darken it to #1477CB to reach 4.5:1, or #0F5998 for 7:1.

What is the complementary color of #7cbcf2?

#F2B27C sits directly opposite on the wheel. Softer options are the split-complements #F27C81 and #F2ED7C, which give the same contrast with far less vibration.

What colors go well with #7cbcf2?

For interface work: #F4F8FA as the surface, #C0D8ED for borders, #4B769B for secondary text, #BE330E as an accent and #0C4474 for hover and pressed states. For a palette, the analogous pair #7CF2ED and #7C81F2 stays calm, while #F2B27C is the loudest partner.

What is #7cbcf2 in CMYK for printing?

cmyk(49%, 22%, 0%, 5%). 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 #7cbcf2 warm or cool?

Cool — it scores 99 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #7C91F2; nudged cooler, #63AAF1.

Which Tailwind color is closest to #7cbcf2?

The sky family — its 500 step is #0ea5e9, ΔE2000 9.4 away. That is a visible difference, so define #7cbcf2 as a custom token rather than reaching for the built-in.

How do I use #7cbcf2 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#7cbcf2] or text-[#7cbcf2], 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 #7cbcf2 with 50% opacity?

rgba(124, 188, 242, 0.5), or #7cbcf280 in eight-digit hex. Over white that composites to #BEDEF9; over black, #3E5E79.

Is #7cbcf2 a web-safe color?

No. The nearest web-safe colour is #66CCFF, ΔE2000 6.6 away. The palette only matters for legacy displays and some email clients now.

What does the color #7cbcf2 mean?

As a blue, it reads trusted, calm, competent. 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 effect is amplified — it will dominate whatever sits beside it.

What gradient works with #7cbcf2?
