What colors go with orange red

Each match keeps orange red'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 orange red 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.

#00baff

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.

#00ffc5

#003aff

Triadic

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

#00ff45

#4500ff

Analogous

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

#ff003b

#ffc500

Tints and shades of orange red

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

Tints (lighter)

A UI color palette built from orange red

The eight semantic roles an interface actually uses, derived from orange red 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.

accent: #003aff
background: #fdfcfc

Using orange red in an interface

Orange is the classic accent for a blue or teal interface: it is the complement, and it reads as an object rather than a surface. Keep it to buttons, badges and single highlights; as a background it competes with everything on top of it. Whichever role orange red 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.
