How to use #9da3c1

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 #31364E
Safe as a 1px border on white
No — use #8A91B5

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.

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.

#9da3c1, answered

What color is #9da3c1?

#9da3c1 is a light soft blue, closest to Light Steel Blue (ΔE2000 10.5). It sits at 230° on the hue wheel with 23% saturation and 69% lightness, which reads as cool.

What is the RGB value of #9da3c1?

rgb(157, 163, 193) — 157 red, 163 green and 193 blue out of 255, or 61.6% / 63.9% / 75.7% by channel.

What is #9da3c1 in HSL and HSV?

hsl(230, 23%, 69%) and hsv(230, 19%, 76%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #9da3c1 a light or a dark color?

It is a mid-tone. Relative luminance is 0.3721 and perceived brightness is 65%, so black text on it reaches 8.44:1.

Should I use black or white text on #9da3c1?

Black. It scores 8.44:1 against #9da3c1, versus 2.49:1 for white — AAA at any size.

Is #9da3c1 accessible on a white background?

#9da3c1 on white scores 2.49:1, which fails WCAG AA at every size. Darken it to #6B74A1 to reach 4.5:1, or #4E567C for 7:1.

What is the complementary color of #9da3c1?

#C1BB9D sits directly opposite on the wheel. Softer options are the split-complements #C1A99D and #B5C19D, which give the same contrast with far less vibration.

What colors go well with #9da3c1?

For interface work: #F6F6F9 as the surface, #CDD0DF for borders, #59628D for secondary text, #816A4B as an accent and #31364E for hover and pressed states. For a palette, the analogous pair #9DB5C1 and #A99DC1 stays calm, while #C1BB9D is the loudest partner.

What is #9da3c1 in CMYK for printing?

cmyk(19%, 16%, 0%, 24%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #9da3c1 warm or cool?

Cool — it scores 75 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #A49DC1; nudged cooler, #9BACC3.

Which Tailwind color is closest to #9da3c1?

The slate family — its 500 step is #64748b, ΔE2000 18.1 away. That is a visible difference, so define #9da3c1 as a custom token rather than reaching for the built-in.

How do I use #9da3c1 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#9da3c1] or text-[#9da3c1], 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 #9da3c1 with 50% opacity?

rgba(157, 163, 193, 0.5), or #9da3c180 in eight-digit hex. Over white that composites to #CED1E0; over black, #4F5261.

Is #9da3c1 a web-safe color?

No. The nearest web-safe colour is #9999CC, ΔE2000 6.2 away. The palette only matters for legacy displays and some email clients now.

What does the color #9da3c1 mean?
