Engines & appsConstructors for Unity, Unreal, Godot, Flutter, SwiftUI and Android.

Unity Color	`new Color(0.957f, 0.247f, 0.369f, 1.0f)`Color for everyday scripting (0–1). Color32 when you need whole numbers from 0 to 255.
Unity Color32	`new Color32(244, 63, 94, 255)`
Unreal FLinearColor	`FLinearColor(0.9047f, 0.0497f, 0.1119f, 1.0f)`FLinearColor for materials and lighting. FColor when you need whole numbers from 0 to 255.
Unreal FColor	`FColor(244, 63, 94, 255)`Whole numbers from 0 to 255 — use when an API asks for FColor, not FLinearColor.
Godot Color	`Color(0.957, 0.247, 0.369, 1)`
Flutter Color	`Color(0xFFF43F5E)`Packed ARGB, so alpha comes first.
Android Color	`Color.rgb(244, 63, 94)`
SwiftUI Color	`Color(red: 0.957, green: 0.247, blue: 0.369)`
UIKit UIColor	`UIColor(red: 0.957, green: 0.247, blue: 0.369, alpha: 1)`

Contrast and accessibility

WCAG 2 ratios are what audits and legislation reference. APCA is shown alongside because WCAG 2 is known to misjudge mid-tone backgrounds, and it is the basis of the WCAG 3 draft.
