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

Unity Color	`new Color(1.0f, 0.647f, 0.0f, 1.0f)`Color for everyday scripting (0–1). Color32 when you need whole numbers from 0 to 255.
Unity Color32	`new Color32(255, 165, 0, 255)`
Unreal FLinearColor	`FLinearColor(1.0f, 0.3763f, 0.0f, 1.0f)`FLinearColor for materials and lighting. FColor when you need whole numbers from 0 to 255.
Unreal FColor	`FColor(255, 165, 0, 255)`Whole numbers from 0 to 255 — use when an API asks for FColor, not FLinearColor.
Godot Color	`Color(1, 0.647, 0, 1)`
Flutter Color	`Color(0xFFFFA500)`Packed ARGB, so alpha comes first.
Android Color	`Color.rgb(255, 165, 0)`
SwiftUI Color	`Color(red: 1, green: 0.647, blue: 0)`
UIKit UIColor	`UIColor(red: 1, green: 0.647, 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
Orange on white	1.97:1	Fail	Lc 38	Non-text elements only
Orange on black	10.63:1	AAA	Lc 65	Headings and large text
