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 #9ba1af

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
  • Brand accents, badges and data highlights
Use with care
  • Text of any size on white — fails WCAG AA
  • 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 #393D47
Safe as a 1px border on white
No — use #8D94A4

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 mid lightness keeps it versatile in both themes.

Worth knowing

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

Transparency

What each alpha value actually composites to. The top row is #9ba1af over white; the bottom row is the same alpha over a checkerboard, so you can see what survives on a photo or a video.

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.

#9ba1af, answered

What color is #9ba1af?

#9ba1af is a balanced muted blue, closest to Dark Gray (ΔE2000 7.2). It sits at 222° on the hue wheel with 11% saturation and 65% lightness, which reads as cool.

What is the RGB value of #9ba1af?

rgb(155, 161, 175) — 155 red, 161 green and 175 blue out of 255, or 60.8% / 63.1% / 68.6% by channel.

What is #9ba1af in HSL and HSV?

hsl(222, 11%, 65%) and hsv(222, 11%, 69%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #9ba1af a light or a dark color?

It is a mid-tone. Relative luminance is 0.3555 and perceived brightness is 63%, so black text on it reaches 8.11:1.

Should I use black or white text on #9ba1af?

Black. It scores 8.11:1 against #9ba1af, versus 2.59:1 for white — AAA at any size.

Is #9ba1af accessible on a white background?

#9ba1af on white scores 2.59:1, which fails WCAG AA at every size. Darken it to #6E778A to reach 4.5:1, or #535968 for 7:1.

What is the complementary color of #9ba1af?

#AFA99B sits directly opposite on the wheel. Softer options are the split-complements #AF9F9B and #ABAF9B, which give the same contrast with far less vibration.

What colors go well with #9ba1af?

For interface work: #F7F7F8 as the surface, #D2D4DB for borders, #666E7F for secondary text, #766556 as an accent and #393D47 for hover and pressed states. For a palette, the analogous pair #9BABAF and #9F9BAF stays calm, while #AFA99B is the loudest partner.

What is #9ba1af in CMYK for printing?

cmyk(11%, 8%, 0%, 31%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #9ba1af warm or cool?

Cool — it scores 64 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #9C9BAF; nudged cooler, #99A4B1.

Which Tailwind color is closest to #9ba1af?

The gray family — its 500 step is #6b7280, ΔE2000 16.8 away. That is a visible difference, so define #9ba1af as a custom token rather than reaching for the built-in.

How do I use #9ba1af in Tailwind CSS?

Inline it as an arbitrary value with bg-[#9ba1af] or text-[#9ba1af], 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 #9ba1af with 50% opacity?

rgba(155, 161, 175, 0.5), or #9ba1af80 in eight-digit hex. Over white that composites to #CDD0D7; over black, #4E5158.

Is #9ba1af a web-safe color?

No. The nearest web-safe colour is #999999, ΔE2000 7.2 away. The palette only matters for legacy displays and some email clients now.

What does the color #9ba1af 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 #9ba1af?

The safest is same-hue elevation: linear-gradient(135deg, #BDC1CA, #9ba1af 45%, #393D47). For more colour, a short hue run to #958AA1 keeps it rich without turning muddy.
