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 #b2eeff

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
  • Thin strokes and 1px borders — they disappear on light UI
  • 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 #006380
Safe as a 1px border on white
No — use #009FCB

Meaning and mood

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

cleantechnicalfreshclinical

Cyan reads as water, air and infrastructure: cool, hygienic, engineered.

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

At high lightness it disappears into white surfaces and thin strokes vanish entirely.

Transparency

What each alpha value actually composites to. The top row is #b2eeff 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.

#b2eeff, answered

What color is #b2eeff?

#b2eeff is a light electric cyan, closest to Powder Blue (ΔE2000 5). It sits at 193° on the hue wheel with 100% saturation and 85% lightness, which reads as cool.

What is the RGB value of #b2eeff?

rgb(178, 238, 255) — 178 red, 238 green and 255 blue out of 255, or 69.8% / 93.3% / 100% by channel.

What is #b2eeff in HSL and HSV?

hsl(193, 100%, 85%) and hsv(193, 30%, 100%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #b2eeff a light or a dark color?

It is a light color. Relative luminance is 0.7783 and perceived brightness is 88%, so black text on it reaches 16.57:1.

Should I use black or white text on #b2eeff?

Black. It scores 16.57:1 against #b2eeff, versus 1.27:1 for white — AAA at any size.

Is #b2eeff accessible on a white background?

#b2eeff on white scores 1.27:1, which fails WCAG AA at every size. Darken it to #007FA3 to reach 4.5:1, or #005F7A for 7:1.

What is the complementary color of #b2eeff?

#FFC3B2 sits directly opposite on the wheel. Softer options are the split-complements #FFB2C8 and #FFE9B2, which give the same contrast with far less vibration.

What colors go well with #b2eeff?

For interface work: #F4F9FA as the surface, #C0E3ED for borders, #4B899B for secondary text, #CC0005 as an accent and #006380 for hover and pressed states. For a palette, the analogous pair #B2FFE9 and #B2C8FF stays calm, while #FFC3B2 is the loudest partner.

What is #b2eeff in CMYK for printing?

cmyk(30%, 7%, 0%, 0%). 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 #b2eeff warm or cool?

Cool — it scores 93 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #B2FFF4; nudged cooler, #B2DDFF.

Which Tailwind color is closest to #b2eeff?

The cyan family — its 500 step is #06b6d4, ΔE2000 17.4 away. That is a visible difference, so define #b2eeff as a custom token rather than reaching for the built-in.

How do I use #b2eeff in Tailwind CSS?

Inline it as an arbitrary value with bg-[#b2eeff] or text-[#b2eeff], 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 #b2eeff with 50% opacity?

rgba(178, 238, 255, 0.5), or #b2eeff80 in eight-digit hex. Over white that composites to #D9F7FF; over black, #597780.

Is #b2eeff a web-safe color?

No. The nearest web-safe colour is #99FFFF, ΔE2000 9.9 away. The palette only matters for legacy displays and some email clients now.

What does the color #b2eeff mean?

As a cyan, it reads clean, technical, fresh. Cyan reads as water, air and infrastructure: cool, hygienic, engineered. At this chroma the effect is amplified — it will dominate whatever sits beside it.

What gradient works with #b2eeff?

The safest is same-hue elevation: linear-gradient(135deg, #EBFBFF, #b2eeff 45%, #006380). For more colour, a short hue run to #9397FF keeps it rich without turning muddy.
