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 #d2dfff

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 #002580
Safe as a 1px border on white
No — use #628FFF

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.

What each alpha value actually composites to. The top row is #d2dfff 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.

#d2dfff, answered

What color is #d2dfff?

#d2dfff is a pale electric blue, closest to Lavender (ΔE2000 6.2). It sits at 223° on the hue wheel with 100% saturation and 91% lightness, which reads as cool.

What is the RGB value of #d2dfff?

rgb(210, 223, 255) — 210 red, 223 green and 255 blue out of 255, or 82.4% / 87.5% / 100% by channel.

What is #d2dfff in HSL and HSV?

hsl(223, 100%, 91%) and hsv(223, 18%, 100%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #d2dfff a light or a dark color?

It is a light color. Relative luminance is 0.7370 and perceived brightness is 88%, so black text on it reaches 15.74:1.

Should I use black or white text on #d2dfff?

Black. It scores 15.74:1 against #d2dfff, versus 1.33:1 for white — AAA at any size.

Is #d2dfff accessible on a white background?

#d2dfff on white scores 1.33:1, which fails WCAG AA at every size. Darken it to #2F6BFF to reach 4.5:1, or #0042E7 for 7:1.

What is the complementary color of #d2dfff?

#FFF2D2 sits directly opposite on the wheel. Softer options are the split-complements #FFDCD2 and #F6FFD2, which give the same contrast with far less vibration.

What colors go well with #d2dfff?

For interface work: #F4F6FA as the surface, #C0CDED for borders, #4B629B for secondary text, #CC5F00 as an accent and #002580 for hover and pressed states. For a palette, the analogous pair #D2F6FF and #DCD2FF stays calm, while #FFF2D2 is the loudest partner.

What is #d2dfff in CMYK for printing?

cmyk(18%, 13%, 0%, 0%). 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 #d2dfff warm or cool?

Cool — it scores 93 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #D6D2FF; nudged cooler, #D2E6FF.

Which Tailwind color is closest to #d2dfff?

The sky family — its 500 step is #0ea5e9, ΔE2000 25.3 away. That is a visible difference, so define #d2dfff as a custom token rather than reaching for the built-in.

How do I use #d2dfff in Tailwind CSS?

Inline it as an arbitrary value with bg-[#d2dfff] or text-[#d2dfff], 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 #d2dfff with 50% opacity?

rgba(210, 223, 255, 0.5), or #d2dfff80 in eight-digit hex. Over white that composites to #E9EFFF; over black, #697080.

Is #d2dfff a web-safe color?

No. The nearest web-safe colour is #CCCCFF, ΔE2000 7.2 away. The palette only matters for legacy displays and some email clients now.

What does the color #d2dfff 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 #d2dfff?

The safest is same-hue elevation: linear-gradient(135deg, #EBF0FF, #d2dfff 45%, #002580). For more colour, a short hue run to #D6B4FF keeps it rich without turning muddy.
