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 #bdfeef

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 #027E61
Safe as a 1px border on white
No — use #03A580

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.

#bdfeef, answered

What color is #bdfeef?

#bdfeef is a pale electric cyan, closest to Pale Turquoise (ΔE2000 6.5). It sits at 166° on the hue wheel with 97% saturation and 87% lightness, which reads as cool.

What is the RGB value of #bdfeef?

rgb(189, 254, 239) — 189 red, 254 green and 239 blue out of 255, or 74.1% / 99.6% / 93.7% by channel.

What is #bdfeef in HSL and HSV?

hsl(166, 97%, 87%) and hsv(166, 26%, 100%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #bdfeef a light or a dark color?

It is a light color. Relative luminance is 0.8793 and perceived brightness is 92%, so black text on it reaches 18.59:1.

Should I use black or white text on #bdfeef?

Black. It scores 18.59:1 against #bdfeef, versus 1.13:1 for white — AAA at any size.

Is #bdfeef accessible on a white background?

#bdfeef on white scores 1.13:1, which fails WCAG AA at every size. Darken it to #028265 to reach 4.5:1, or #02644D for 7:1.

What is the complementary color of #bdfeef?

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

What colors go well with #bdfeef?

For interface work: #F4FAF9 as the surface, #C0EDE2 for borders, #4B9B88 for secondary text, #CC0062 as an accent and #027E61 for hover and pressed states. For a palette, the analogous pair #BDFECF and #BDEDFE stays calm, while #FEBDCC is the loudest partner.

What is #bdfeef in CMYK for printing?

cmyk(26%, 0%, 6%, 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 #bdfeef warm or cool?

Cool — it scores 82 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #BDFED7; nudged cooler, #BDF6FF.

Which Tailwind color is closest to #bdfeef?

The teal family — its 500 step is #14b8a6, ΔE2000 20.5 away. That is a visible difference, so define #bdfeef as a custom token rather than reaching for the built-in.

How do I use #bdfeef in Tailwind CSS?

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

rgba(189, 254, 239, 0.5), or #bdfeef80 in eight-digit hex. Over white that composites to #DEFFF7; over black, #5F7F78.

Is #bdfeef a web-safe color?

No. The nearest web-safe colour is #CCFFFF, ΔE2000 6.5 away. The palette only matters for legacy displays and some email clients now.

What does the color #bdfeef 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 #bdfeef?

The safest is same-hue elevation: linear-gradient(135deg, #EBFFFA, #bdfeef 45%, #027E61). For more colour, a short hue run to #9FCCFE keeps it rich without turning muddy.
