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 #a7afbc

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

Works well for
  • Text and icons on dark surfaces
  • Borders, dividers and quiet backgrounds
  • Long-form reading 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 #373E48
Safe as a 1px border on white
No — use #8A95A6

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.

With almost no chroma left, the family association is barely present; treat it as a neutral that happens to lean this way. 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.

Bottom row of hexes is the flattened result over white — use those when a design tool refuses transparency, or when you need a solid fallback.

#a7afbc, answered

What color is #a7afbc?

#a7afbc is a light muted blue, closest to Dark Gray (ΔE2000 6.7). It sits at 217° on the hue wheel with 14% saturation and 70% lightness, which reads as cool.

What is the RGB value of #a7afbc?

rgb(167, 175, 188) — 167 red, 175 green and 188 blue out of 255, or 65.5% / 68.6% / 73.7% by channel.

What is #a7afbc in HSL and HSV?

hsl(217, 14%, 70%) and hsv(217, 11%, 74%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #a7afbc a light or a dark color?

It is a mid-tone. Relative luminance is 0.4251 and perceived brightness is 68%, so black text on it reaches 9.50:1.

Should I use black or white text on #a7afbc?

Black. It scores 9.50:1 against #a7afbc, versus 2.21:1 for white — AAA at any size.

Is #a7afbc accessible on a white background?

#a7afbc on white scores 2.21:1, which fails WCAG AA at every size. Darken it to #69768A to reach 4.5:1, or #4F5867 for 7:1.

What is the complementary color of #a7afbc?

#BCB4A7 sits directly opposite on the wheel. Softer options are the split-complements #BCA9A7 and #B9BCA7, which give the same contrast with far less vibration.

What colors go well with #a7afbc?

For interface work: #F6F7F8 as the surface, #D1D5DC for borders, #636F82 for secondary text, #786154 as an accent and #373E48 for hover and pressed states. For a palette, the analogous pair #A7B9BC and #A9A7BC stays calm, while #BCB4A7 is the loudest partner.

What is #a7afbc in CMYK for printing?

cmyk(11%, 7%, 0%, 26%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #a7afbc warm or cool?

Cool — it scores 68 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #A7A7BC; nudged cooler, #97A4B3.

Which Tailwind color is closest to #a7afbc?

The sky family — its 500 step is #0ea5e9, ΔE2000 20.1 away. That is a visible difference, so define #a7afbc as a custom token rather than reaching for the built-in.

How do I use #a7afbc in Tailwind CSS?

Inline it as an arbitrary value with bg-[#a7afbc] or text-[#a7afbc], 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 #a7afbc with 50% opacity?

rgba(167, 175, 188, 0.5), or #a7afbc80 in eight-digit hex. Over white that composites to #D3D7DE; over black, #54585E.

Is #a7afbc a web-safe color?

No. The nearest web-safe colour is #9999CC, ΔE2000 13.4 away. The palette only matters for legacy displays and some email clients now.

What does the color #a7afbc 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 low chroma the association is faint; it behaves more like a neutral.

What gradient works with #a7afbc?

The safest is same-hue elevation: linear-gradient(135deg, #CACFD6, #a7afbc 45%, #373E48). For more colour, a short hue run to #9F96AF keeps it rich without turning muddy.
