I have been striping for 45 years. If you want Apple green I agree you would be safer picking a standard color from the 1 Shot palette. You really cant mix 1 shot colors to get the exact color because they are not true mixing colors. Striping paint is oil based so trying to do it with a different type of paint really does not work, it does not flow while "pulling" a line. It needs to dry REAL slow to work correctly.
