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 #8fcaf0

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 #0F4A70
Safe as a 1px border on white
No — use #2C9BE3

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.

Transparency

What each alpha value actually composites to. The top row is #8fcaf0 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.

#8fcaf0, answered

What color is #8fcaf0?

#8fcaf0 is a light electric blue, closest to Light Sky Blue (ΔE2000 1.9). It sits at 204° on the hue wheel with 76% saturation and 75% lightness, which reads as cool.

What is the RGB value of #8fcaf0?

rgb(143, 202, 240) — 143 red, 202 green and 240 blue out of 255, or 56.1% / 79.2% / 94.1% by channel.

What is #8fcaf0 in HSL and HSV?

hsl(204, 76%, 75%) and hsv(204, 40%, 94%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #8fcaf0 a light or a dark color?

It is a light color. Relative luminance is 0.5437 and perceived brightness is 75%, so black text on it reaches 11.87:1.

Should I use black or white text on #8fcaf0?

Black. It scores 11.87:1 against #8fcaf0, versus 1.77:1 for white — AAA at any size.

Is #8fcaf0 accessible on a white background?

#8fcaf0 on white scores 1.77:1, which fails WCAG AA at every size. Darken it to #197AB9 to reach 4.5:1, or #135C8C for 7:1.

What is the complementary color of #8fcaf0?

#F0B58F sits directly opposite on the wheel. Softer options are the split-complements #F08F9A and #F0E68F, which give the same contrast with far less vibration.

What colors go well with #8fcaf0?

For interface work: #F4F8FA as the surface, #C0DBED for borders, #4B7B9B for secondary text, #B92B13 as an accent and #0F4A70 for hover and pressed states. For a palette, the analogous pair #8FF0E6 and #8F9AF0 stays calm, while #F0B58F is the loudest partner.

What is #8fcaf0 in CMYK for printing?

cmyk(40%, 16%, 0%, 6%). 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 #8fcaf0 warm or cool?

Cool — it scores 97 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #8FEEF0; nudged cooler, #77B5EF.

Which Tailwind color is closest to #8fcaf0?

The cyan family — its 500 step is #06b6d4, ΔE2000 12.6 away. That is a visible difference, so define #8fcaf0 as a custom token rather than reaching for the built-in.

How do I use #8fcaf0 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#8fcaf0] or text-[#8fcaf0], 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 #8fcaf0 with 50% opacity?

rgba(143, 202, 240, 0.5), or #8fcaf080 in eight-digit hex. Over white that composites to #C7E5F8; over black, #486578.

Is #8fcaf0 a web-safe color?

No. The nearest web-safe colour is #99CCFF, ΔE2000 4.3 away. The palette only matters for legacy displays and some email clients now.

What does the color #8fcaf0 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 #8fcaf0?
