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 #e3ddfb

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 #220D72
Safe as a 1px border on white
No — use #9882F0

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 high lightness makes it recede — a surface colour rather than a statement.

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 #e3ddfb 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.

#e3ddfb, answered

What color is #e3ddfb?

#e3ddfb is a pale electric blue, closest to Lavender (ΔE2000 4.7). It sits at 252° on the hue wheel with 79% saturation and 93% lightness, which reads as cool.

What is the RGB value of #e3ddfb?

rgb(227, 221, 251) — 227 red, 221 green and 251 blue out of 255, or 89% / 86.7% / 98.4% by channel.

What is #e3ddfb in HSL and HSV?

hsl(252, 79%, 93%) and hsv(252, 12%, 98%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #e3ddfb a light or a dark color?

It is a light color. Relative luminance is 0.7501 and perceived brightness is 89%, so black text on it reaches 16.00:1.

Should I use black or white text on #e3ddfb?

Black. It scores 16.00:1 against #e3ddfb, versus 1.31:1 for white — AAA at any size.

Is #e3ddfb accessible on a white background?

#e3ddfb on white scores 1.31:1, which fails WCAG AA at every size. Darken it to #7A5DEC to reach 4.5:1, or #542FE7 for 7:1.

What is the complementary color of #e3ddfb?

#F5FBDD sits directly opposite on the wheel. Softer options are the split-complements #FBF2DD and #E6FBDD, which give the same contrast with far less vibration.

What colors go well with #e3ddfb?

For interface work: #F6F4FA as the surface, #C9C0ED for borders, #5B4B9B for secondary text, #BCB110 as an accent and #220D72 for hover and pressed states. For a palette, the analogous pair #DDE6FB and #F2DDFB stays calm, while #F5FBDD is the loudest partner.

What is #e3ddfb in CMYK for printing?

cmyk(10%, 12%, 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 #e3ddfb 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 #EEDDFB; nudged cooler, #DCE2FB.

Which Tailwind color is closest to #e3ddfb?

The sky family — its 500 step is #0ea5e9, ΔE2000 32.9 away. That is a visible difference, so define #e3ddfb as a custom token rather than reaching for the built-in.

How do I use #e3ddfb in Tailwind CSS?

Inline it as an arbitrary value with bg-[#e3ddfb] or text-[#e3ddfb], 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 #e3ddfb with 50% opacity?

rgba(227, 221, 251, 0.5), or #e3ddfb80 in eight-digit hex. Over white that composites to #F1EEFD; over black, #726F7E.

Is #e3ddfb a web-safe color?

No. The nearest web-safe colour is #CCCCFF, ΔE2000 7.5 away. The palette only matters for legacy displays and some email clients now.

What does the color #e3ddfb 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 #e3ddfb?
