Unity Color	`new Color(0.867f, 0.627f, 0.867f, 1.0f)`Color for everyday scripting (0–1). Color32 when you need whole numbers from 0 to 255.
Unity Color32	`new Color32(221, 160, 221, 255)`
Unreal FLinearColor	`FLinearColor(0.7231f, 0.3515f, 0.7231f, 1.0f)`FLinearColor for materials and lighting. FColor when you need whole numbers from 0 to 255.
Unreal FColor	`FColor(221, 160, 221, 255)`Whole numbers from 0 to 255 — use when an API asks for FColor, not FLinearColor.

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
Plum on white	2.07:1	Fail	Lc 40	Non-text elements only
Plum on black	10.15:1	AAA	Lc 62	Headings and large text
