Problem:

    Are the inks of the greens in Excel gum, M & M's, Sharpie markers, Wet Erase markers, Washable Crayola markers, and Highlighters mixtures of the same colors?

My Guess:

    I think that the dyes in Excel gum, M & M's, Sharpies, Wet Erase markers, Washable markers, and Highlighters will be mixtures of different colors based on the information that I have gathered.
