Answer 1

Unless you're using negative inputs, Add won't reduce the amount of blue, red, or green. Since you're adding red light into grey, you'll get pink as a result. Instead, you should use Multiply.

Multiply the base texture with a white-based color map, where the color map is white where it shouldn't affect the base texture. To make the white-based color map, you can invert the result of the color mask and add it to the result of the multiply you already have.
