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 #badffb

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
  • 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 #074878
Safe as a 1px border on white
No — use #259AF2

Meaning and mood

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

trustedcalmcompetentcorporate

The default of institutions for a reason: blue is read as stable and safe across nearly every culture that has been surveyed.

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

It is also the most crowded hue on the web. Distinctiveness has to come from your other choices.

#badffb, answered

What color is #badffb?

#badffb is a pale electric blue, closest to Light Blue (ΔE2000 6.6). It sits at 206° on the hue wheel with 89% saturation and 86% lightness, which reads as cool.

What is the RGB value of #badffb?

rgb(186, 223, 251) — 186 red, 223 green and 251 blue out of 255, or 72.9% / 87.5% / 98.4% by channel.

What is #badffb in HSL and HSV?

hsl(206, 89%, 86%) and hsv(206, 26%, 98%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #badffb a light or a dark color?

It is a light color. Relative luminance is 0.7018 and perceived brightness is 85%, so black text on it reaches 15.04:1.

Should I use black or white text on #badffb?

Black. It scores 15.04:1 against #badffb, versus 1.40:1 for white — AAA at any size.

Is #badffb accessible on a white background?

#badffb on white scores 1.40:1, which fails WCAG AA at every size. Darken it to #0C78C9 to reach 4.5:1, or #095B99 for 7:1.

What is the complementary color of #badffb?

#FBD6BA sits directly opposite on the wheel. Softer options are the split-complements #FBBABF and #FBF6BA, which give the same contrast with far less vibration.

What colors go well with #badffb?

For interface work: #F4F8FA as the surface, #C0D9ED for borders, #4B789B for secondary text, #C42A08 as an accent and #074878 for hover and pressed states. For a palette, the analogous pair #BAFBF6 and #BABFFB stays calm, while #FBD6BA is the loudest partner.

What is #badffb in CMYK for printing?

cmyk(26%, 11%, 0%, 2%). 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 #badffb warm or cool?

Cool — it scores 98 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #BAC7FB; nudged cooler, #A1CDFB.

Which Tailwind color is closest to #badffb?

The cyan family — its 500 step is #06b6d4, ΔE2000 18.3 away. That is a visible difference, so define #badffb as a custom token rather than reaching for the built-in.

How do I use #badffb in Tailwind CSS?

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

rgba(186, 223, 251, 0.5), or #badffb80 in eight-digit hex. Over white that composites to #DDEFFD; over black, #5D707E.

Is #badffb a web-safe color?

No. The nearest web-safe colour is #CCCCFF, ΔE2000 13.8 away. The palette only matters for legacy displays and some email clients now.

What does the color #badffb mean?

As a blue, it reads trusted, calm, competent. The default of institutions for a reason: blue is read as stable and safe across nearly every culture that has been surveyed. At this chroma the effect is amplified — it will dominate whatever sits beside it.

What gradient works with #badffb?

The safest is same-hue elevation: linear-gradient(135deg, #ECF6FE, #badffb 45%, #074878). For more colour, a short hue run to #AE9DF9 keeps it rich without turning muddy.
