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

Unity Color	`new Color(0.831f, 0.831f, 0.847f, 1.0f)`Color for everyday scripting (0–1). Color32 when you need whole numbers from 0 to 255.
Unity Color32	`new Color32(212, 212, 216, 255)`
Unreal FLinearColor	`FLinearColor(0.6584f, 0.6584f, 0.6867f, 1.0f)`FLinearColor for materials and lighting. FColor when you need whole numbers from 0 to 255.
Unreal FColor	`FColor(212, 212, 216, 255)`Whole numbers from 0 to 255 — use when an API asks for FColor, not FLinearColor.
Godot Color	`Color(0.831, 0.831, 0.847, 1)`
Flutter Color	`Color(0xFFD4D4D8)`Packed ARGB, so alpha comes first.
Android Color	`Color.rgb(212, 212, 216)`
SwiftUI Color	`Color(red: 0.831, green: 0.831, blue: 0.847)`

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.

Pairing	WCAG 2 ratio	Level	APCA	Suitable for
