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 #b5fafd

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 #03777C
Safe as a 1px border on white
No — use #05A2A9

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 high lightness makes it recede — a surface colour rather than a statement.

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 #b5fafd 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.

#b5fafd, answered

What color is #b5fafd?

#b5fafd is a pale electric cyan, closest to Pale Turquoise (ΔE2000 2.8). It sits at 183° on the hue wheel with 95% saturation and 85% lightness, which reads as cool.

What is the RGB value of #b5fafd?

rgb(181, 250, 253) — 181 red, 250 green and 253 blue out of 255, or 71% / 98% / 99.2% by channel.

What is #b5fafd in HSL and HSV?

hsl(183, 95%, 85%) and hsv(183, 28%, 99%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #b5fafd a light or a dark color?

It is a light color. Relative luminance is 0.8529 and perceived brightness is 91%, so black text on it reaches 18.06:1.

Should I use black or white text on #b5fafd?

Black. It scores 18.06:1 against #b5fafd, versus 1.16:1 for white — AAA at any size.

Is #b5fafd accessible on a white background?

#b5fafd on white scores 1.16:1, which fails WCAG AA at every size. Darken it to #048187 to reach 4.5:1, or #036064 for 7:1.

What is the complementary color of #b5fafd?

#FDB8B5 sits directly opposite on the wheel. Softer options are the split-complements #FDB5D6 and #FDDCB5, which give the same contrast with far less vibration.

What colors go well with #b5fafd?

For interface work: #F4FAFA as the surface, #C0EBED for borders, #4B989B for secondary text, #CC0029 as an accent and #03777C for hover and pressed states. For a palette, the analogous pair #B5FDDC and #B5D6FD stays calm, while #FDB8B5 is the loudest partner.

What is #b5fafd in CMYK for printing?

cmyk(29%, 1%, 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 #b5fafd warm or cool?

Cool — it scores 89 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #B5FDE6; nudged cooler, #B4E1FE.

Which Tailwind color is closest to #b5fafd?

The cyan family — its 500 step is #06b6d4, ΔE2000 20 away. That is a visible difference, so define #b5fafd as a custom token rather than reaching for the built-in.

How do I use #b5fafd in Tailwind CSS?

Inline it as an arbitrary value with bg-[#b5fafd] or text-[#b5fafd], 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 #b5fafd with 50% opacity?

rgba(181, 250, 253, 0.5), or #b5fafd80 in eight-digit hex. Over white that composites to #DAFDFE; over black, #5B7D7F.

Is #b5fafd a web-safe color?

No. The nearest web-safe colour is #CCFFFF, ΔE2000 3.6 away. The palette only matters for legacy displays and some email clients now.

What does the color #b5fafd 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 #b5fafd?

The safest is same-hue elevation: linear-gradient(135deg, #EBFEFE, #b5fafd 45%, #03777C). For more colour, a short hue run to #97ACFC keeps it rich without turning muddy.
