Unity Color	`new Color(0.906f, 0.435f, 0.318f, 1.0f)`Color for everyday scripting (0–1). Color32 when you need whole numbers from 0 to 255.
Unity Color32	`new Color32(231, 111, 81, 255)`
Unreal FLinearColor	`FLinearColor(0.7991f, 0.159f, 0.0823f, 1.0f)`FLinearColor for materials and lighting. FColor when you need whole numbers from 0 to 255.
Unreal FColor	`FColor(231, 111, 81, 255)`Whole numbers from 0 to 255 — use when an API asks for FColor, not FLinearColor.
Godot Color	`Color(0.906, 0.435, 0.318, 1)`
Flutter Color	`Color(0xFFE76F51)`Packed ARGB, so alpha comes first.

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
Burnt Sienna on white	3.09:1	AA Large	Lc 57	Large headings only
