What is the hex code for Light Cyan?

Light Cyan is #e0ffff. In CSS the keyword lightcyan, the hex #e0ffff, rgb(224, 255, 255) and hsl(180, 100%, 94%) all paint the same color.

What is the opposite of Light Cyan on the color wheel?

The opposite (complementary) color is #ffe0e0, the same saturation and lightness rotated 180° around the HSL wheel. Complementary pairs give the strongest contrast, which is why the complement should be used sparingly rather than at equal weight.

Can I use Light Cyan for text?

Light Cyan as text on white has a contrast ratio of 1.05:1, which fails WCAG AA for body text (4.5:1) and for large text (3:1). On black it is 19.92:1, which passes for body text. Use it as text on dark surfaces, or as a fill with dark text on top.

Light Cyan color: hex #e0ffff, RGB and HSL

Light Cyan is the CSS keyword lightcyan, hex #e0ffff, rgb(224, 255, 255), hsl(180, 100%, 94%). It is a very light, fully saturated cyan in the blues family. Below: the colors that go with it, its tints and shades, how it reads as text, and a complete interface palette built from it.

CSS name: lightcyan
Hex: #e0ffff
RGB: rgb(224, 255, 255)
HSL: hsl(180, 100%, 94%)
On white: 1.05:1 — fails AA; use as a fill, not text
On black: 19.92:1 — passes AA for body text

.example {
  color: lightcyan;          /* keyword */
  color: #e0ffff;          /* hex */
  color: rgb(224, 255, 255); /* rgb */
  color: hsl(180, 100%, 94%); /* hsl */
}

What colors go with light cyan

Each match keeps light cyan's saturation and lightness and rotates only the hue, so the relationship is the wheel's and nothing else. Any of these can be an accent beside light cyan as the primary; the harmony guides explain which rule suits which interface.

Complementary

The opposite hue, 180° away — the strongest contrast, best kept to one accent per screen.

#ffe0e0

Split-complementary

The two neighbors of the complement, at 150° and 210° — most of the contrast with less tension, and two accents instead of one.

#ffe0f0

#fff0e0

Triadic

Two hues at 120° and 240° — three evenly spaced signals, the scheme charts and category colors want.

#ffe0ff

#ffffe0 · lightyellow

Analogous

The neighbors at −30° and +30° — calm and cohesive, with emphasis coming from weight and size rather than hue.

#e0fff0

#e0f0ff

Tints and shades of light cyan

Tints add lightness toward white; shades remove it toward black. The hue and saturation stay fixed, so every step still reads as light cyan — these are the hover, pressed, disabled and surface variants a single brand color needs.

Tints (lighter)

#eaffff

#f0ffff · azure

#f5ffff

#faffff

Shades (darker)

A UI color palette built from light cyan

The eight semantic roles an interface actually uses, derived from light cyan as the primary with the split-complementary rule: secondary and accent rotate around the wheel, and the five neutrals take the hue at lightness steps tuned for light and dark mode. This is the same derivation the palette generator runs — open it there to change the rule, drag the anchors, or export the set as CSS variables.

secondary: #ffe0f0
accent: #fff0e0
background: #fcfdfd

Dark mode

Using light cyan in an interface

Blue is the default interface color for a reason: it sits comfortably behind content, it has a wide usable lightness range for hover and pressed states, and its complement (orange) leaves red and green free for status. Most of the good primaries in this set are here. Whichever role light cyan takes, define it once as a token rather than repeating the keyword: the semantic palette guide covers the eight roles, and the guides to complementary, triadic and the other color schemes explain how to weight the matches above.

What is the hex code for Light Cyan?: Light Cyan is #e0ffff. In CSS the keyword lightcyan, the hex #e0ffff, rgb(224, 255, 255) and hsl(180, 100%, 94%) all paint the same color.
