What colors go with sky blue

Each match keeps sky blue'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 sky blue 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.

#eba487

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.

#eb879c

#ebd687

Triadic

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

#eb87ce

#ceeb87

Analogous

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

#87ebd6

#879ceb

Tints and shades of sky blue

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

A UI color palette built from sky blue

The eight semantic roles an interface actually uses, derived from sky blue 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.

Using sky blue 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 sky blue 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.
