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

Unity Color	`new Color(0.0f, 0.392f, 0.0f, 1.0f)`Color for everyday scripting (0–1). Color32 when you need whole numbers from 0 to 255.
Unity Color32	`new Color32(0, 100, 0, 255)`
Unreal FLinearColor	`FLinearColor(0.0f, 0.1274f, 0.0f, 1.0f)`FLinearColor for materials and lighting. FColor when you need whole numbers from 0 to 255.
Unreal FColor	`FColor(0, 100, 0, 255)`Whole numbers from 0 to 255 — use when an API asks for FColor, not FLinearColor.
Godot Color	`Color(0, 0.392, 0, 1)`
Flutter Color	`Color(0xFF006400)`Packed ARGB, so alpha comes first.
Android Color	`Color.rgb(0, 100, 0)`
SwiftUI Color	`Color(red: 0, green: 0.392, blue: 0)`
UIKit UIColor	`UIColor(red: 0, green: 0.392, blue: 0, 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.

Pairing	WCAG 2 ratio	Level	APCA	Suitable for
Dark Green on white	7.44:1	AAA	Lc 85	Body text, 18px and up
Dark Green on black	2.82:1	Fail	Lc 17	Not usable for text
