UKismetMathLibrary::EqualEqual_LinearColorLinearColor

function Engine Blueprint Since 4.0

#include "Kismet/KismetMathLibrary.h"

Access: public Specifiers: staticUFUNCTIONBlueprintPure

Description

Returns true if A and B are exactly equal (A == B) on all four channels. This is the Blueprint == operator for LinearColor.

Caveats & Gotchas

• Performs exact floating-point comparison — two colors produced independently through arithmetic are unlikely to be exactly equal even if they represent the same logical color. Use LinearColor_IsNearEqual with a tolerance for arithmetic results.
• Despite the header comment mentioning "error tolerance", this function takes no tolerance parameter and performs an exact == comparison.

Signature

static UE_INL_API bool EqualEqual_LinearColorLinearColor(FLinearColor A, FLinearColor B);

Parameters

Name	Type	Description	Default
A	FLinearColor	First color.	—
B	FLinearColor	Second color.	—

Return Type

bool

Example

Compare against a literal color constant C++

FLinearColor Current = GetCurrentColor();
if (UKismetMathLibrary::EqualEqual_LinearColorLinearColor(Current, FLinearColor::Black))
{
    // Exactly black — only reliable for constants, not computed values
}
