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 #abafd1

Derived from its contrast, chroma and lightness — not from taste.

Works well for
  • Text and icons on dark surfaces
  • Charts, tags and secondary surfaces
  • Card and section backgrounds
  • Brand accents, badges and data highlights
Use with care
  • Text of any size on white — fails WCAG AA
  • 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 #2D3152
Safe as a 1px border on white
No — use #8A90BF

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.

The muted chroma softens the association — it reads considered rather than loud, which suits long-form and data-heavy screens. 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.

#abafd1, answered

What color is #abafd1?

#abafd1 is a light soft blue, closest to Light Steel Blue (ΔE2000 9). It sits at 234° on the hue wheel with 29% saturation and 75% lightness, which reads as cool.

What is the RGB value of #abafd1?

rgb(171, 175, 209) — 171 red, 175 green and 209 blue out of 255, or 67.1% / 68.6% / 82% by channel.

What is #abafd1 in HSL and HSV?

hsl(234, 29%, 75%) and hsv(234, 18%, 82%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #abafd1 a light or a dark color?

It is a mid-tone. Relative luminance is 0.4392 and perceived brightness is 70%, so black text on it reaches 9.78:1.

Should I use black or white text on #abafd1?

Black. It scores 9.78:1 against #abafd1, versus 2.15:1 for white — AAA at any size.

Is #abafd1 accessible on a white background?

#abafd1 on white scores 2.15:1, which fails WCAG AA at every size. Darken it to #6970AD to reach 4.5:1, or #4D538C for 7:1.

What is the complementary color of #abafd1?

#D1CDAB sits directly opposite on the wheel. Softer options are the split-complements #D1BAAB and #C2D1AB, which give the same contrast with far less vibration.

What colors go well with #abafd1?

For interface work: #F5F6FA as the surface, #CACDE2 for borders, #515894 for secondary text, #886F44 as an accent and #2D3152 for hover and pressed states. For a palette, the analogous pair #ABC2D1 and #BAABD1 stays calm, while #D1CDAB is the loudest partner.

What is #abafd1 in CMYK for printing?

cmyk(18%, 16%, 0%, 18%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #abafd1 warm or cool?

Cool — it scores 81 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #B5ABD1; nudged cooler, #AABAD2.

Which Tailwind color is closest to #abafd1?

The slate family — its 500 step is #64748b, ΔE2000 21.9 away. That is a visible difference, so define #abafd1 as a custom token rather than reaching for the built-in.

How do I use #abafd1 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#abafd1] or text-[#abafd1], 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 #abafd1 with 50% opacity?

rgba(171, 175, 209, 0.5), or #abafd180 in eight-digit hex. Over white that composites to #D5D7E8; over black, #565869.

Is #abafd1 a web-safe color?

No. The nearest web-safe colour is #9999CC, ΔE2000 7.4 away. The palette only matters for legacy displays and some email clients now.

What does the color #abafd1 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 moderate chroma the association is present but not shouted.

What gradient works with #abafd1?

The safest is same-hue elevation: linear-gradient(135deg, #D3D5E7, #abafd1 45%, #2D3152). For more colour, a short hue run to #B597C6 keeps it rich without turning muddy.
