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

Unity Color	`new Color(0.941f, 1.0f, 1.0f, 1.0f)`Color for everyday scripting (0–1). Color32 when you need whole numbers from 0 to 255.
Unity Color32	`new Color32(240, 255, 255, 255)`
Unreal FLinearColor	`FLinearColor(0.8714f, 1.0f, 1.0f, 1.0f)`FLinearColor for materials and lighting. FColor when you need whole numbers from 0 to 255.
Unreal FColor	`FColor(240, 255, 255, 255)`Whole numbers from 0 to 255 — use when an API asks for FColor, not FLinearColor.
Godot Color	`Color(0.941, 1, 1, 1)`
Flutter Color	`Color(0xFFF0FFFF)`Packed ARGB, so alpha comes first.
Android Color	`Color.rgb(240, 255, 255)`

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
Azure on white	1.03:1	Fail	Lc 0	Not usable for text
Azure on black	20.45:1	AAA	Lc 106	Body text at any size
