Change one color on a 2d pawn

Hello i need your help, how can i change the color on a specific part of the pawn?
The pawn is a 2d sprite.

You will need to do this in the material editor with a lerp node.

Create a black and white mask. White where the color will change and black where it should remain the untouched.

I try but this is the result I don’t know why do that black background

what kind of image format and program do you use to create the texture?

I use a PNG with a transparent background. The bottom pin can then be used to remove the background. You also need to change the blend to either transparent or masked. My images can be found below.

It work!!!

thank you so much
