Masking sharing features between Sculpt and Texture Paint Modes

I know that masking inside Sculpt Mode and Texture Paint is completely different, but i think can be beneficial if they share features.

• Option to change the default Black color Mask in Scult Mode. (Sculpting with Black Textures or dark Matcaps without forcing to go back to a blank matcap to work, invert colors(?), etc
• Texture Mask color with alpha or gradient slidder option, to see between 0 or 1 (Inverted)
