How to use #b09ff2

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 #230F70
Safe as a 1px border on white
No — use #9A84EE

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.

What each alpha value actually composites to. The top row is #b09ff2 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.

#b09ff2, answered

What color is #b09ff2?

#b09ff2 is a light electric blue, closest to Light Steel Blue (ΔE2000 12.1). It sits at 252° on the hue wheel with 76% saturation and 79% lightness, which reads as cool.

What is the RGB value of #b09ff2?

rgb(176, 159, 242) — 176 red, 159 green and 242 blue out of 255, or 69% / 62.4% / 94.9% by channel.

What is #b09ff2 in HSL and HSV?

hsl(252, 76%, 79%) and hsv(252, 34%, 95%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #b09ff2 a light or a dark color?

It is a mid-tone. Relative luminance is 0.4044 and perceived brightness is 69%, so black text on it reaches 9.09:1.

Should I use black or white text on #b09ff2?

Black. It scores 9.09:1 against #b09ff2, versus 2.31:1 for white — AAA at any size.

Is #b09ff2 accessible on a white background?

#b09ff2 on white scores 2.31:1, which fails WCAG AA at every size. Darken it to #795CE9 to reach 4.5:1, or #5733E3 for 7:1.

What is the complementary color of #b09ff2?

#E1F29F sits directly opposite on the wheel. Softer options are the split-complements #F2D99F and #B7F29F, which give the same contrast with far less vibration.

What colors go well with #b09ff2?

For interface work: #F6F4FA as the surface, #C9C0ED for borders, #5B4B9B for secondary text, #B7B015 as an accent and #230F70 for hover and pressed states. For a palette, the analogous pair #9FB7F2 and #D99FF2 stays calm, while #E1F29F is the loudest partner.

What is #b09ff2 in CMYK for printing?

cmyk(27%, 34%, 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 #b09ff2 warm or cool?

Cool — it scores 77 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #CE9FF2; nudged cooler, #9EACF3.

Which Tailwind color is closest to #b09ff2?

The purple family — its 500 step is #a855f7, ΔE2000 18.7 away. That is a visible difference, so define #b09ff2 as a custom token rather than reaching for the built-in.

How do I use #b09ff2 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#b09ff2] or text-[#b09ff2], 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 #b09ff2 with 50% opacity?

rgba(176, 159, 242, 0.5), or #b09ff280 in eight-digit hex. Over white that composites to #D8CFF9; over black, #585079.

Is #b09ff2 a web-safe color?

No. The nearest web-safe colour is #9999FF, ΔE2000 6.1 away. The palette only matters for legacy displays and some email clients now.
