Syntax
struct FColor
Remarks
FColor Stores a color with 8 bits of precision per channel. Note: Linear color values should always be converted to gamma space before stored in an FColor, as 8 bits of precision is not enough to store linear space colors! This can be done with FLinearColor::ToFColor(true)
