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 #aa91df

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 #331D63
Safe as a 1px border on white
No — use #A185DC

Meaning and mood

What a colour in this family tends to signal, and how this particular chroma and lightness change the reading.

creativepremiummodernimaginative

Violet sits between the warmth of red and the calm of blue, so it reads as inventive without reading as risky. Current shorthand for software craft.

This is a confident chroma: strong enough to lead a brand, restrained enough to live in an interface all day. The lightness keeps it airy and approachable.

Worth knowing

Deep violets swallow detail on screens with poor gamma; check it on a cheap laptop panel.

Transparency

What each alpha value actually composites to. The top row is #aa91df 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.

#aa91df, answered

What color is #aa91df?

#aa91df is a light vivid violet, closest to Medium Purple (ΔE2000 10.3). It sits at 259° on the hue wheel with 55% saturation and 72% lightness, which reads as cool.

What is the RGB value of #aa91df?

rgb(170, 145, 223) — 170 red, 145 green and 223 blue out of 255, or 66.7% / 56.9% / 87.5% by channel.

What is #aa91df in HSL and HSV?

hsl(259, 55%, 72%) and hsv(259, 35%, 87%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #aa91df a light or a dark color?

It is a mid-tone. Relative luminance is 0.3412 and perceived brightness is 64%, so black text on it reaches 7.82:1.

Should I use black or white text on #aa91df?

Black. It scores 7.82:1 against #aa91df, versus 2.68:1 for white — AAA at any size.

Is #aa91df accessible on a white background?

#aa91df on white scores 2.68:1, which fails WCAG AA at every size. Darken it to #8562D1 to reach 4.5:1, or #673AC6 for 7:1.

What is the complementary color of #aa91df?

#C6DF91 sits directly opposite on the wheel. Softer options are the split-complements #DFD191 and #9FDF91, which give the same contrast with far less vibration.

What colors go well with #aa91df?

For interface work: #F6F4FA as the surface, #CEC0ED for borders, #644B9B for secondary text, #9AA22A as an accent and #331D63 for hover and pressed states. For a palette, the analogous pair #919FDF and #D191DF stays calm, while #C6DF91 is the loudest partner.

What is #aa91df in CMYK for printing?

cmyk(24%, 35%, 0%, 13%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #aa91df warm or cool?

Cool — it scores 73 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #C791DF; nudged cooler, #9094E0.

Which Tailwind color is closest to #aa91df?

The purple family — its 500 step is #a855f7, ΔE2000 15.8 away. That is a visible difference, so define #aa91df as a custom token rather than reaching for the built-in.

How do I use #aa91df in Tailwind CSS?

Inline it as an arbitrary value with bg-[#aa91df] or text-[#aa91df], 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 #aa91df with 50% opacity?

rgba(170, 145, 223, 0.5), or #aa91df80 in eight-digit hex. Over white that composites to #D5C8EF; over black, #554970.

Is #aa91df a web-safe color?

No. The nearest web-safe colour is #9999CC, ΔE2000 6.7 away. The palette only matters for legacy displays and some email clients now.

What does the color #aa91df mean?

As a violet, it reads creative, premium, modern. Violet sits between the warmth of red and the calm of blue, so it reads as inventive without reading as risky. Current shorthand for software craft. At this chroma the effect is amplified — it will dominate whatever sits beside it.

What gradient works with #aa91df?

The safest is same-hue elevation: linear-gradient(135deg, #CFC1ED, #aa91df 45%, #331D63). For more colour, a short hue run to #D879D2 keeps it rich without turning muddy.
