Trying to make RGB lighting

How do I...?

I’m trying to make a game with lights that slowly change colors like RGB lights you see in a gamer’s room. But I can’t find any tutorial on how to do it. Does anyone know how to do it?

IDK about lights but i know about color
You use color conversion extension

To convert RGB to HSL

Hue Saturation Lightness

I do not remember exactly but its easy to check
Saturation you need at 100
Lightness at 50 or 100 but lets assume 50
And Hue can be anything from 0 to 360

So H 360 S 100 L 50

Now instead of 360 you put there some number variable lets call it HuVar from Hue Variable

And now you change somethings color to

ColorConversion::HslToRgb(HuVar, 100, 50)

In separate event you add 2 actions
Change variable HuVar add 1
Change variable HuVar set to mod(HuVar,360)

And now it will cycle trough all colors
