Mixing in a gallon of dark latex paint will offer up some coloring when your panit job get nicked! Many of my MM props get nicks and dings on the and the base color which is ususally a dark grat comes through it generally isnt noticable. On some of the MM props, that base color is my finished color with a few shadows added. Mixing in that gallon sure beats having the stark white drywall mud showing.....As far as moving into the 21st century....no thanks! MM is quick and easy!
