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 #8baeef

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 #0F3170
Safe as a 1px border on white
No — use #6392E9

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 #8baeef 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.

#8baeef, answered

What color is #8baeef?

#8baeef is a light electric blue, closest to Cornflower Blue (ΔE2000 7.8). It sits at 219° on the hue wheel with 76% saturation and 74% lightness, which reads as cool.

What is the RGB value of #8baeef?

rgb(139, 174, 239) — 139 red, 174 green and 239 blue out of 255, or 54.5% / 68.2% / 93.7% by channel.

What is #8baeef in HSL and HSV?

hsl(219, 76%, 74%) and hsv(219, 42%, 94%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #8baeef a light or a dark color?

It is a mid-tone. Relative luminance is 0.4199 and perceived brightness is 68%, so black text on it reaches 9.40:1.

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

Black. It scores 9.40:1 against #8baeef, versus 2.23:1 for white — AAA at any size.

Is #8baeef accessible on a white background?

#8baeef on white scores 2.23:1, which fails WCAG AA at every size. Darken it to #316FE3 to reach 4.5:1, or #1951B8 for 7:1.

What is the complementary color of #8baeef?

#EFCC8B sits directly opposite on the wheel. Softer options are the split-complements #EF9A8B and #E0EF8B, which give the same contrast with far less vibration.

What colors go well with #8baeef?

For interface work: #F4F6FA as the surface, #C0CFED for borders, #4B679B for secondary text, #B85514 as an accent and #0F3170 for hover and pressed states. For a palette, the analogous pair #8BE0EF and #9A8BEF stays calm, while #EFCC8B is the loudest partner.

What is #8baeef in CMYK for printing?

cmyk(42%, 27%, 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 #8baeef 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 #8D8BEF; nudged cooler, #73A8EE.

Which Tailwind color is closest to #8baeef?

The sky family — its 500 step is #0ea5e9, ΔE2000 13.7 away. That is a visible difference, so define #8baeef as a custom token rather than reaching for the built-in.

How do I use #8baeef in Tailwind CSS?

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

rgba(139, 174, 239, 0.5), or #8baeef80 in eight-digit hex. Over white that composites to #C5D7F7; over black, #465778.

Is #8baeef a web-safe color?

No. The nearest web-safe colour is #9999FF, ΔE2000 8.6 away. The palette only matters for legacy displays and some email clients now.

What does the color #8baeef 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 #8baeef?

The safest is same-hue elevation: linear-gradient(135deg, #C1D3F6, #8baeef 45%, #0F3170). For more colour, a short hue run to #A170EB keeps it rich without turning muddy.
