How to use #a19bc9

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 #322D53
Safe as a 1px border on white
No — use #948EC2

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.

Transparency

What each alpha value actually composites to. The top row is #a19bc9 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.

#a19bc9, answered

What color is #a19bc9?

#a19bc9 is a light soft blue, closest to Plum (ΔE2000 13.7). It sits at 248° on the hue wheel with 30% saturation and 70% lightness, which reads as cool.

What is the RGB value of #a19bc9?

rgb(161, 155, 201) — 161 red, 155 green and 201 blue out of 255, or 63.1% / 60.8% / 78.8% by channel.

What is #a19bc9 in HSL and HSV?

hsl(248, 30%, 70%) and hsv(248, 23%, 79%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #a19bc9 a light or a dark color?

It is a mid-tone. Relative luminance is 0.3524 and perceived brightness is 64%, so black text on it reaches 8.05:1.

Should I use black or white text on #a19bc9?

Black. It scores 8.05:1 against #a19bc9, versus 2.61:1 for white — AAA at any size.

Is #a19bc9 accessible on a white background?

#a19bc9 on white scores 2.61:1, which fails WCAG AA at every size. Darken it to #756DB0 to reach 4.5:1, or #595094 for 7:1.

What is the complementary color of #a19bc9?

#C3C99B sits directly opposite on the wheel. Softer options are the split-complements #C9B89B and #ACC99B, which give the same contrast with far less vibration.

What colors go well with #a19bc9?

For interface work: #F6F5FA as the surface, #CDCAE2 for borders, #595095 for secondary text, #888144 as an accent and #322D53 for hover and pressed states. For a palette, the analogous pair #9BACC9 and #B89BC9 stays calm, while #C3C99B is the loudest partner.

What is #a19bc9 in CMYK for printing?

cmyk(20%, 23%, 0%, 21%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #a19bc9 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 #B29BC9; nudged cooler, #99A5CB.

Which Tailwind color is closest to #a19bc9?

The slate family — its 500 step is #64748b, ΔE2000 19.2 away. That is a visible difference, so define #a19bc9 as a custom token rather than reaching for the built-in.

How do I use #a19bc9 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#a19bc9] or text-[#a19bc9], 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 #a19bc9 with 50% opacity?

rgba(161, 155, 201, 0.5), or #a19bc980 in eight-digit hex. Over white that composites to #D0CDE4; over black, #514E65.

Is #a19bc9 a web-safe color?

No. The nearest web-safe colour is #9999CC, ΔE2000 2.7 away. The palette only matters for legacy displays and some email clients now.

What does the color #a19bc9 mean?
