I downloaded a generic model of a shoe that had a base texture, normal map, and roughness associated with it. On the base texture the shoe is either black and white. I was wondering if I could section each part of the base texture to change the color. I wouldn't be to do it in Photoshop because the texture is mostly just black and white and it would change all blacks or whites instead of sectioning off each part. Here's a picture of an example of how I would like to change the color:
How would I go about just changing the selected mesh to a different color such as red while still keeping the base texture?
