How to use #9da5cb

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 #2C3353
Safe as a 1px border on white
No — use #8993C0

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.

#9da5cb, answered

What color is #9da5cb?

#9da5cb is a light soft blue, closest to Light Steel Blue (ΔE2000 10.3). It sits at 230° on the hue wheel with 31% saturation and 71% lightness, which reads as cool.

What is the RGB value of #9da5cb?

rgb(157, 165, 203) — 157 red, 165 green and 203 blue out of 255, or 61.6% / 64.7% / 79.6% by channel.

What is #9da5cb in HSL and HSV?

hsl(230, 31%, 71%) and hsv(230, 23%, 80%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #9da5cb a light or a dark color?

It is a mid-tone. Relative luminance is 0.3839 and perceived brightness is 66%, so black text on it reaches 8.68:1.

Should I use black or white text on #9da5cb?

Black. It scores 8.68:1 against #9da5cb, versus 2.42:1 for white — AAA at any size.

Is #9da5cb accessible on a white background?

#9da5cb on white scores 2.42:1, which fails WCAG AA at every size. Darken it to #6471AD to reach 4.5:1, or #4A558B for 7:1.

What is the complementary color of #9da5cb?

#CBC39D sits directly opposite on the wheel. Softer options are the split-complements #CBAC9D and #BCCB9D, which give the same contrast with far less vibration.

What colors go well with #9da5cb?

For interface work: #F5F6FA as the surface, #CACEE3 for borders, #505C96 for secondary text, #896B43 as an accent and #2C3353 for hover and pressed states. For a palette, the analogous pair #9DBCCB and #AC9DCB stays calm, while #CBC39D is the loudest partner.

What is #9da5cb in CMYK for printing?

cmyk(23%, 19%, 0%, 20%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #9da5cb warm or cool?

Cool — it scores 84 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #A69DCB; nudged cooler, #9CB0CD.

Which Tailwind color is closest to #9da5cb?

The blue family — its 500 step is #3b82f6, ΔE2000 18.7 away. That is a visible difference, so define #9da5cb as a custom token rather than reaching for the built-in.

How do I use #9da5cb in Tailwind CSS?

Inline it as an arbitrary value with bg-[#9da5cb] or text-[#9da5cb], 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 #9da5cb with 50% opacity?

rgba(157, 165, 203, 0.5), or #9da5cb80 in eight-digit hex. Over white that composites to #CED2E5; over black, #4F5366.

Is #9da5cb a web-safe color?

No. The nearest web-safe colour is #9999CC, ΔE2000 4.7 away. The palette only matters for legacy displays and some email clients now.

What does the color #9da5cb 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 #9da5cb?

The safest is same-hue elevation: linear-gradient(135deg, #C5CAE0, #9da5cb 45%, #2C3353). For more colour, a short hue run to #A989C0 keeps it rich without turning muddy.
