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 #cccdf9

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 #0D1072
Safe as a 1px border on white
No — use #878AF1

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.

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.

#cccdf9, answered

What color is #cccdf9?

#cccdf9 is a pale electric blue, closest to Lavender (ΔE2000 9.2). It sits at 239° on the hue wheel with 79% saturation and 89% lightness, which reads as cool.

What is the RGB value of #cccdf9?

rgb(204, 205, 249) — 204 red, 205 green and 249 blue out of 255, or 80% / 80.4% / 97.6% by channel.

What is #cccdf9 in HSL and HSV?

hsl(239, 79%, 89%) and hsv(239, 18%, 98%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #cccdf9 a light or a dark color?

It is a light color. Relative luminance is 0.6334 and perceived brightness is 82%, so black text on it reaches 13.67:1.

Should I use black or white text on #cccdf9?

Black. It scores 13.67:1 against #cccdf9, versus 1.54:1 for white — AAA at any size.

Is #cccdf9 accessible on a white background?

#cccdf9 on white scores 1.54:1, which fails WCAG AA at every size. Darken it to #6366ED to reach 4.5:1, or #3539E7 for 7:1.

What is the complementary color of #cccdf9?

#F9F8CC sits directly opposite on the wheel. Softer options are the split-complements #F9E1CC and #E3F9CC, which give the same contrast with far less vibration.

What colors go well with #cccdf9?

For interface work: #F4F4FA as the surface, #C0C1ED for borders, #4B4C9B for secondary text, #BA8C12 as an accent and #0D1072 for hover and pressed states. For a palette, the analogous pair #CCE3F9 and #E1CCF9 stays calm, while #F9F8CC is the loudest partner.

What is #cccdf9 in CMYK for printing?

cmyk(18%, 18%, 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 #cccdf9 warm or cool?

Cool — it scores 84 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #DBCCF9; nudged cooler, #CBDDFA.

Which Tailwind color is closest to #cccdf9?

The sky family — its 500 step is #0ea5e9, ΔE2000 27.2 away. That is a visible difference, so define #cccdf9 as a custom token rather than reaching for the built-in.

How do I use #cccdf9 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#cccdf9] or text-[#cccdf9], 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 #cccdf9 with 50% opacity?

rgba(204, 205, 249, 0.5), or #cccdf980 in eight-digit hex. Over white that composites to #E6E6FC; over black, #66677D.

Is #cccdf9 a web-safe color?

No. The nearest web-safe colour is #CCCCFF, ΔE2000 1.7 away. The palette only matters for legacy displays and some email clients now.

What does the color #cccdf9 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 #cccdf9?

The safest is same-hue elevation: linear-gradient(135deg, #EDEDFD, #cccdf9 45%, #0D1072). For more colour, a short hue run to #E3B1F6 keeps it rich without turning muddy.
