UKismetMathLibrary::HSVToRGB

function Engine Blueprint Since 4.0

#include "Kismet/KismetMathLibrary.h"

Access: public Specifiers: staticUFUNCTIONBlueprintPure

Description

Constructs a FLinearColor in linear RGB space from individual hue, saturation, and value components. The preferred Blueprint node for generating colors from HSV parameters when each component is a separate float.

Caveats & Gotchas

• H must be in [0, 360) — values outside this range are not clamped or wrapped automatically and can produce incorrect output. Use FMath::Fmod(H, 360.0f) to wrap if your hue might exceed 360.
• The result is linear RGB, not sRGB. Plugging the output directly into a UI color field that expects sRGB (e.g., a UMG Image tint) may look too bright.

Signature

static UE_INL_API FLinearColor HSVToRGB(float H, float S, float V, float A = 1.0f)

Parameters

Name	Type	Description	Default
H	float	Hue in degrees [0.0, 360.0).	—
S	float	Saturation in [0.0, 1.0].	—
V	float	Value (brightness) in [0.0, 1.0].	—
A	float	Alpha in [0.0, 1.0].	1.0f

Return Type

FLinearColor

Example

Generate a vivid color from a hue angle C++

float Hue = 200.0f; // blue-ish
FLinearColor Color = UKismetMathLibrary::HSVToRGB(Hue, 1.0f, 1.0f);
DecalComponent->SetDecalColor(Color);
