How to use #87b0fc

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 #032E7C
Safe as a 1px border on white
No — use #5A93FB

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.

What each alpha value actually composites to. The top row is #87b0fc 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.

#87b0fc, answered

What color is #87b0fc?

#87b0fc is a light electric blue, closest to Cornflower Blue (ΔE2000 8). It sits at 219° on the hue wheel with 95% saturation and 76% lightness, which reads as cool.

What is the RGB value of #87b0fc?

rgb(135, 176, 252) — 135 red, 176 green and 252 blue out of 255, or 52.9% / 69% / 98.8% by channel.

What is #87b0fc in HSL and HSV?

hsl(219, 95%, 76%) and hsv(219, 46%, 99%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #87b0fc a light or a dark color?

It is a mid-tone. Relative luminance is 0.4323 and perceived brightness is 69%, so black text on it reaches 9.65:1.

Should I use black or white text on #87b0fc?

Black. It scores 9.65:1 against #87b0fc, versus 2.18:1 for white — AAA at any size.

Is #87b0fc accessible on a white background?

#87b0fc on white scores 2.18:1, which fails WCAG AA at every size. Darken it to #1F6BF9 to reach 4.5:1, or #054CD0 for 7:1.

What is the complementary color of #87b0fc?

#FCD387 sits directly opposite on the wheel. Softer options are the split-complements #FC9987 and #EAFC87, which give the same contrast with far less vibration.

What colors go well with #87b0fc?

For interface work: #F4F6FA as the surface, #C0CFED for borders, #4B679B for secondary text, #CA5102 as an accent and #032E7C for hover and pressed states. For a palette, the analogous pair #87EAFC and #9987FC stays calm, while #FCD387 is the loudest partner.

What is #87b0fc in CMYK for printing?

cmyk(46%, 30%, 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 #87b0fc warm or cool?

Cool — it scores 95 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #8987FC; nudged cooler, #6DAAFD.

Which Tailwind color is closest to #87b0fc?

The sky family — its 500 step is #0ea5e9, ΔE2000 13.3 away. That is a visible difference, so define #87b0fc as a custom token rather than reaching for the built-in.

How do I use #87b0fc in Tailwind CSS?

Inline it as an arbitrary value with bg-[#87b0fc] or text-[#87b0fc], 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 #87b0fc with 50% opacity?

rgba(135, 176, 252, 0.5), or #87b0fc80 in eight-digit hex. Over white that composites to #C3D8FE; over black, #44587E.

Is #87b0fc a web-safe color?

No. The nearest web-safe colour is #9999FF, ΔE2000 9.6 away. The palette only matters for legacy displays and some email clients now.

What does the color #87b0fc mean?
