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 #acb3c3

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 #353C4A
Safe as a 1px border on white
No — use #8C95AC

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.

#acb3c3, answered

What color is #acb3c3?

#acb3c3 is a light soft blue, closest to Light Steel Blue (ΔE2000 6.4). It sits at 222° on the hue wheel with 16% saturation and 72% lightness, which reads as cool.

What is the RGB value of #acb3c3?

rgb(172, 179, 195) — 172 red, 179 green and 195 blue out of 255, or 67.5% / 70.2% / 76.5% by channel.

What is #acb3c3 in HSL and HSV?

hsl(222, 16%, 72%) and hsv(222, 12%, 76%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #acb3c3 a light or a dark color?

It is a mid-tone. Relative luminance is 0.4495 and perceived brightness is 70%, so black text on it reaches 9.99:1.

Should I use black or white text on #acb3c3?

Black. It scores 9.99:1 against #acb3c3, versus 2.10:1 for white — AAA at any size.

Is #acb3c3 accessible on a white background?

#acb3c3 on white scores 2.10:1, which fails WCAG AA at every size. Darken it to #697591 to reach 4.5:1, or #4F586E for 7:1.

What is the complementary color of #acb3c3?

#C3BCAC sits directly opposite on the wheel. Softer options are the split-complements #C3B1AC and #BFC3AC, which give the same contrast with far less vibration.

What colors go well with #acb3c3?

For interface work: #F6F7F9 as the surface, #D0D4DD for borders, #606C85 for secondary text, #7B6451 as an accent and #353C4A for hover and pressed states. For a palette, the analogous pair #ACBFC3 and #B1ACC3 stays calm, while #C3BCAC is the loudest partner.

What is #acb3c3 in CMYK for printing?

cmyk(12%, 8%, 0%, 24%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #acb3c3 warm or cool?

Cool — it scores 70 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #AEACC3; nudged cooler, #ABB6C5.

Which Tailwind color is closest to #acb3c3?

The sky family — its 500 step is #0ea5e9, ΔE2000 21.4 away. That is a visible difference, so define #acb3c3 as a custom token rather than reaching for the built-in.

How do I use #acb3c3 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#acb3c3] or text-[#acb3c3], 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 #acb3c3 with 50% opacity?

rgba(172, 179, 195, 0.5), or #acb3c380 in eight-digit hex. Over white that composites to #D6D9E1; over black, #565A62.

Is #acb3c3 a web-safe color?

No. The nearest web-safe colour is #99CCCC, ΔE2000 17.4 away. The palette only matters for legacy displays and some email clients now.

What does the color #acb3c3 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 #acb3c3?

The safest is same-hue elevation: linear-gradient(135deg, #D0D4DD, #acb3c3 45%, #353C4A). For more colour, a short hue run to #A79AB6 keeps it rich without turning muddy.
