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 #b3eeeb

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 #176864
Safe as a 1px border on white
No — use #24A29B

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.

This is a confident chroma: strong enough to lead a brand, restrained enough to live in an interface all day. 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 #b3eeeb 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.

#b3eeeb, answered

What color is #b3eeeb?

#b3eeeb is a light vivid cyan, closest to Pale Turquoise (ΔE2000 1.3). It sits at 177° on the hue wheel with 63% saturation and 82% lightness, which reads as cool.

What is the RGB value of #b3eeeb?

rgb(179, 238, 235) — 179 red, 238 green and 235 blue out of 255, or 70.2% / 93.3% / 92.2% by channel.

What is #b3eeeb in HSL and HSV?

hsl(177, 63%, 82%) and hsv(177, 25%, 93%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #b3eeeb a light or a dark color?

It is a light color. Relative luminance is 0.7673 and perceived brightness is 87%, so black text on it reaches 16.35:1.

Should I use black or white text on #b3eeeb?

Black. It scores 16.35:1 against #b3eeeb, versus 1.28:1 for white — AAA at any size.

Is #b3eeeb accessible on a white background?

#b3eeeb on white scores 1.28:1, which fails WCAG AA at every size. Darken it to #1D807B to reach 4.5:1, or #16635F for 7:1.

What is the complementary color of #b3eeeb?

#EEB3B6 sits directly opposite on the wheel. Softer options are the split-complements #EEB3D4 and #EECEB3, which give the same contrast with far less vibration.

What colors go well with #b3eeeb?

For interface work: #F4FAFA as the surface, #C0EDEA for borders, #4B9B97 for secondary text, #AB214B as an accent and #176864 for hover and pressed states. For a palette, the analogous pair #B3EECE and #B3D4EE stays calm, while #EEB3B6 is the loudest partner.

What is #b3eeeb in CMYK for printing?

cmyk(25%, 0%, 1%, 7%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #b3eeeb warm or cool?

Cool — it scores 86 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #B3EED5; nudged cooler, #B2DCEF.

Which Tailwind color is closest to #b3eeeb?

The teal family — its 500 step is #14b8a6, ΔE2000 19 away. That is a visible difference, so define #b3eeeb as a custom token rather than reaching for the built-in.

How do I use #b3eeeb in Tailwind CSS?

Inline it as an arbitrary value with bg-[#b3eeeb] or text-[#b3eeeb], 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 #b3eeeb with 50% opacity?

rgba(179, 238, 235, 0.5), or #b3eeeb80 in eight-digit hex. Over white that composites to #D9F7F5; over black, #5A7776.

Is #b3eeeb a web-safe color?

No. The nearest web-safe colour is #CCFFFF, ΔE2000 4.5 away. The palette only matters for legacy displays and some email clients now.

What does the color #b3eeeb 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 #b3eeeb?

The safest is same-hue elevation: linear-gradient(135deg, #E5F9F8, #b3eeeb 45%, #176864). For more colour, a short hue run to #9AB2E8 keeps it rich without turning muddy.
