Hi, I'm making my game and I need to change the color of my sprite.

I'm testing in this page modified the huv and replace for another color, and work well

But I need to get the same result or similar dynamically ingame.

I'm search in the wiki and found about HSV but I'm new with shaders and no understand about it.

Imgonline's output:

Update : Using a simple code I can change the color, but not that I choose.

You need to convert pixel color to HSV values. Then you modify these values as appropriate, such as by setting desired hue. Then you convert HSV back to RGB and that's your output pixel color.
