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

Unity Color	`new Color(0.518f, 0.8f, 0.086f, 1.0f)`Color for everyday scripting (0–1). Color32 when you need whole numbers from 0 to 255.
Unity Color32	`new Color32(132, 204, 22, 255)`
Unreal FLinearColor	`FLinearColor(0.2307f, 0.6038f, 0.008f, 1.0f)`FLinearColor for materials and lighting. FColor when you need whole numbers from 0 to 255.
Unreal FColor	`FColor(132, 204, 22, 255)`Whole numbers from 0 to 255 — use when an API asks for FColor, not FLinearColor.
Godot Color	`Color(0.518, 0.8, 0.086, 1)`
Flutter Color	`Color(0xFF84CC16)`Packed ARGB, so alpha comes first.
Android Color	`Color.rgb(132, 204, 22)`

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.
