How to use #b5fff2

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 #008069
Safe as a 1px border on white
No — use #00A689

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.

#b5fff2, answered

What color is #b5fff2?

#b5fff2 is a pale electric cyan, closest to Pale Turquoise (ΔE2000 6.1). It sits at 170° on the hue wheel with 100% saturation and 86% lightness, which reads as cool.

What is the RGB value of #b5fff2?

rgb(181, 255, 242) — 181 red, 255 green and 242 blue out of 255, or 71% / 100% / 94.9% by channel.

What is #b5fff2 in HSL and HSV?

hsl(170, 100%, 86%) and hsv(169, 29%, 100%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #b5fff2 a light or a dark color?

It is a light color. Relative luminance is 0.8775 and perceived brightness is 92%, so black text on it reaches 18.55:1.

Should I use black or white text on #b5fff2?

Black. It scores 18.55:1 against #b5fff2, versus 1.13:1 for white — AAA at any size.

Is #b5fff2 accessible on a white background?

#b5fff2 on white scores 1.13:1, which fails WCAG AA at every size. Darken it to #00826B to reach 4.5:1, or #006352 for 7:1.

What is the complementary color of #b5fff2?

#FFB5C2 sits directly opposite on the wheel. Softer options are the split-complements #FFB5E7 and #FFCDB5, which give the same contrast with far less vibration.

What colors go well with #b5fff2?

For interface work: #F4FAF9 as the surface, #C0EDE5 for borders, #4B9B8D for secondary text, #CC0055 as an accent and #008069 for hover and pressed states. For a palette, the analogous pair #B5FFCD and #B5E7FF stays calm, while #FFB5C2 is the loudest partner.

What is #b5fff2 in CMYK for printing?

cmyk(29%, 0%, 5%, 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 #b5fff2 warm or cool?

Cool — it scores 83 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #B5FFD7; nudged cooler, #B5F1FF.

Which Tailwind color is closest to #b5fff2?

The teal family — its 500 step is #14b8a6, ΔE2000 20.1 away. That is a visible difference, so define #b5fff2 as a custom token rather than reaching for the built-in.

How do I use #b5fff2 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#b5fff2] or text-[#b5fff2], 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 #b5fff2 with 50% opacity?

rgba(181, 255, 242, 0.5), or #b5fff280 in eight-digit hex. Over white that composites to #DAFFF9; over black, #5B8079.

Is #b5fff2 a web-safe color?

No. The nearest web-safe colour is #CCFFFF, ΔE2000 6.6 away. The palette only matters for legacy displays and some email clients now.

What does the color #b5fff2 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 #b5fff2?

The safest is same-hue elevation: linear-gradient(135deg, #EBFFFB, #b5fff2 45%, #008069). For more colour, a short hue run to #96C3FF keeps it rich without turning muddy.
