How to use #a28bf3

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

Works well for
  • Text and icons on dark surfaces
  • Primary buttons and calls to action
  • Focus rings, active and selected states
  • Card and section backgrounds
  • Brand accents, badges and data highlights
Use with care
  • Text of any size on white — fails WCAG AA
  • Full-page backgrounds — tiring over long sessions
  • 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 #230C74
Safe as a 1px border on white
No — use #9B82F2

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.

At this chroma the association is amplified — it will dominate anything placed beside it, so give it space and use it sparingly. 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.

#a28bf3, answered

What color is #a28bf3?

#a28bf3 is a light electric blue, closest to Medium Purple (ΔE2000 8.3). It sits at 253° on the hue wheel with 81% saturation and 75% lightness, which reads as cool.

What is the RGB value of #a28bf3?

rgb(162, 139, 243) — 162 red, 139 green and 243 blue out of 255, or 63.5% / 54.5% / 95.3% by channel.

What is #a28bf3 in HSL and HSV?

hsl(253, 81%, 75%) and hsv(253, 43%, 95%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #a28bf3 a light or a dark color?

It is a mid-tone. Relative luminance is 0.3262 and perceived brightness is 63%, so black text on it reaches 7.52:1.

Should I use black or white text on #a28bf3?

Black. It scores 7.52:1 against #a28bf3, versus 2.79:1 for white — AAA at any size.

Is #a28bf3 accessible on a white background?

#a28bf3 on white scores 2.79:1, which fails WCAG AA at every size. Darken it to #7958EE to reach 4.5:1, or #582EE9 for 7:1.

What is the complementary color of #a28bf3?

#DCF38B sits directly opposite on the wheel. Softer options are the split-complements #F3D68B and #A8F38B, which give the same contrast with far less vibration.

What colors go well with #a28bf3?

For interface work: #F6F4FA as the surface, #CAC0ED for borders, #5C4B9B for secondary text, #BEB70E as an accent and #230C74 for hover and pressed states. For a palette, the analogous pair #8BA8F3 and #D68BF3 stays calm, while #DCF38B is the loudest partner.

What is #a28bf3 in CMYK for printing?

cmyk(33%, 43%, 0%, 5%). This is a screen-to-ink approximation — a color this saturated sits outside most CMYK gamuts and will print duller than it looks here.

Is #a28bf3 warm or cool?

Cool — it scores 76 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #C88BF3; nudged cooler, #8A99F4.

Which Tailwind color is closest to #a28bf3?

The violet family — its 500 step is #8b5cf6, ΔE2000 13.1 away. That is a visible difference, so define #a28bf3 as a custom token rather than reaching for the built-in.

How do I use #a28bf3 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#a28bf3] or text-[#a28bf3], 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 #a28bf3 with 50% opacity?

rgba(162, 139, 243, 0.5), or #a28bf380 in eight-digit hex. Over white that composites to #D1C5F9; over black, #51467A.

Is #a28bf3 a web-safe color?

No. The nearest web-safe colour is #9999FF, ΔE2000 5.5 away. The palette only matters for legacy displays and some email clients now.

What does the color #a28bf3 mean?
