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 #ada2fb

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 #14057A
Safe as a 1px border on white
No — use #9385FA

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.

#ada2fb, answered

What color is #ada2fb?

#ada2fb is a light electric blue, closest to Light Steel Blue (ΔE2000 11.1). It sits at 247° on the hue wheel with 92% saturation and 81% lightness, which reads as cool.

What is the RGB value of #ada2fb?

rgb(173, 162, 251) — 173 red, 162 green and 251 blue out of 255, or 67.8% / 63.5% / 98.4% by channel.

What is #ada2fb in HSL and HSV?

hsl(247, 92%, 81%) and hsv(247, 35%, 98%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #ada2fb a light or a dark color?

It is a mid-tone. Relative luminance is 0.4169 and perceived brightness is 70%, so black text on it reaches 9.34:1.

Should I use black or white text on #ada2fb?

Black. It scores 9.34:1 against #ada2fb, versus 2.25:1 for white — AAA at any size.

Is #ada2fb accessible on a white background?

#ada2fb on white scores 2.25:1, which fails WCAG AA at every size. Darken it to #715EF8 to reach 4.5:1, or #462DF6 for 7:1.

What is the complementary color of #ada2fb?

#F0FBA2 sits directly opposite on the wheel. Softer options are the split-complements #FBDAA2 and #C4FBA2, which give the same contrast with far less vibration.

What colors go well with #ada2fb?

For interface work: #F5F4FA as the surface, #C5C0ED for borders, #544B9B for secondary text, #C8AF04 as an accent and #14057A for hover and pressed states. For a palette, the analogous pair #A2C4FB and #DAA2FB stays calm, while #F0FBA2 is the loudest partner.

What is #ada2fb in CMYK for printing?

cmyk(31%, 36%, 0%, 2%). 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 #ada2fb warm or cool?

Cool — it scores 79 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #CEA2FB; nudged cooler, #A1B7FC.

Which Tailwind color is closest to #ada2fb?

The blue family — its 500 step is #3b82f6, ΔE2000 18.7 away. That is a visible difference, so define #ada2fb as a custom token rather than reaching for the built-in.

How do I use #ada2fb in Tailwind CSS?

Inline it as an arbitrary value with bg-[#ada2fb] or text-[#ada2fb], 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 #ada2fb with 50% opacity?

rgba(173, 162, 251, 0.5), or #ada2fb80 in eight-digit hex. Over white that composites to #D6D1FD; over black, #57517E.

Is #ada2fb a web-safe color?

No. The nearest web-safe colour is #9999FF, ΔE2000 4.6 away. The palette only matters for legacy displays and some email clients now.

What does the color #ada2fb 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 chroma the effect is amplified — it will dominate whatever sits beside it.

What gradient works with #ada2fb?

The safest is same-hue elevation: linear-gradient(135deg, #E1DDFE, #ada2fb 45%, #14057A). For more colour, a short hue run to #EB85FA keeps it rich without turning muddy.
