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 #c7beef

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 #271966
Safe as a 1px border on white
No — use #9685E1

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.

This is a confident chroma: strong enough to lead a brand, restrained enough to live in an interface all day. 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.

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.

#c7beef, answered

What color is #c7beef?

#c7beef is a light vivid blue, closest to Thistle (ΔE2000 9.2). It sits at 251° on the hue wheel with 61% saturation and 84% lightness, which reads as cool.

What is the RGB value of #c7beef?

rgb(199, 190, 239) — 199 red, 190 green and 239 blue out of 255, or 78% / 74.5% / 93.7% by channel.

What is #c7beef in HSL and HSV?

hsl(251, 61%, 84%) and hsv(251, 21%, 94%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #c7beef a light or a dark color?

It is a light color. Relative luminance is 0.5520 and perceived brightness is 78%, so black text on it reaches 12.04:1.

Should I use black or white text on #c7beef?

Black. It scores 12.04:1 against #c7beef, versus 1.74:1 for white — AAA at any size.

Is #c7beef accessible on a white background?

#c7beef on white scores 1.74:1, which fails WCAG AA at every size. Darken it to #7964D9 to reach 4.5:1, or #563BCF for 7:1.

What is the complementary color of #c7beef?

#E6EFBE sits directly opposite on the wheel. Softer options are the split-complements #EFDFBE and #CDEFBE, which give the same contrast with far less vibration.

What colors go well with #c7beef?

For interface work: #F5F4FA as the surface, #C8C0ED for borders, #594B9B for secondary text, #A99F23 as an accent and #271966 for hover and pressed states. For a palette, the analogous pair #BECDEF and #DFBEEF stays calm, while #E6EFBE is the loudest partner.

What is #c7beef in CMYK for printing?

cmyk(17%, 21%, 0%, 6%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #c7beef 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 #D9BEEF; nudged cooler, #BDC6F0.

Which Tailwind color is closest to #c7beef?

The blue family — its 500 step is #3b82f6, ΔE2000 26.7 away. That is a visible difference, so define #c7beef as a custom token rather than reaching for the built-in.

How do I use #c7beef in Tailwind CSS?

Inline it as an arbitrary value with bg-[#c7beef] or text-[#c7beef], 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 #c7beef with 50% opacity?

rgba(199, 190, 239, 0.5), or #c7beef80 in eight-digit hex. Over white that composites to #E3DFF7; over black, #645F78.

Is #c7beef a web-safe color?

No. The nearest web-safe colour is #CCCCFF, ΔE2000 4.2 away. The palette only matters for legacy displays and some email clients now.

What does the color #c7beef 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 #c7beef?

The safest is same-hue elevation: linear-gradient(135deg, #F1EFFB, #c7beef 45%, #271966). For more colour, a short hue run to #E4A5E9 keeps it rich without turning muddy.
