Colour vision deficiency

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 #afbbec

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 #182867
Safe as a 1px border on white
No — use #798EDF

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.

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

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

#afbbec, answered

What color is #afbbec?

#afbbec is a light vivid blue, closest to Light Steel Blue (ΔE2000 7.2). It sits at 228° on the hue wheel with 62% saturation and 81% lightness, which reads as cool.

What is the RGB value of #afbbec?

rgb(175, 187, 236) — 175 red, 187 green and 236 blue out of 255, or 68.6% / 73.3% / 92.5% by channel.

What is #afbbec in HSL and HSV?

hsl(228, 62%, 81%) and hsv(228, 26%, 93%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #afbbec a light or a dark color?

It is a light color. Relative luminance is 0.5071 and perceived brightness is 74%, so black text on it reaches 11.14:1.

Should I use black or white text on #afbbec?

Black. It scores 11.14:1 against #afbbec, versus 1.88:1 for white — AAA at any size.

Is #afbbec accessible on a white background?

#afbbec on white scores 1.88:1, which fails WCAG AA at every size. Darken it to #546ED6 to reach 4.5:1, or #2F4CC4 for 7:1.

What is the complementary color of #afbbec?

#ECE0AF sits directly opposite on the wheel. Softer options are the split-complements #ECC2AF and #DAECAF, which give the same contrast with far less vibration.

What colors go well with #afbbec?

For interface work: #F4F5FA as the surface, #C0C9ED for borders, #4B5A9B for secondary text, #A96D23 as an accent and #182867 for hover and pressed states. For a palette, the analogous pair #AFDAEC and #C2AFEC stays calm, while #ECE0AF is the loudest partner.

What is #afbbec in CMYK for printing?

cmyk(26%, 21%, 0%, 8%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #afbbec warm or cool?

Cool — it scores 90 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #B9AFEC; nudged cooler, #AEC8ED.

Which Tailwind color is closest to #afbbec?

The sky family — its 500 step is #0ea5e9, ΔE2000 21 away. That is a visible difference, so define #afbbec as a custom token rather than reaching for the built-in.

How do I use #afbbec in Tailwind CSS?

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

rgba(175, 187, 236, 0.5), or #afbbec80 in eight-digit hex. Over white that composites to #D7DDF6; over black, #585E76.

Is #afbbec a web-safe color?

No. The nearest web-safe colour is #99CCFF, ΔE2000 10.8 away. The palette only matters for legacy displays and some email clients now.

What does the color #afbbec 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 #afbbec?

The safest is same-hue elevation: linear-gradient(135deg, #E1E5F8, #afbbec 45%, #182867). For more colour, a short hue run to #C296E6 keeps it rich without turning muddy.
