Except for throwing out the blue ones, that is exactly what I do. Although I have to ask, how do you apply this portion?
Personally, I start by eating one from each group (in ranbow order) that has the most, as illustrated below. Example:
If I start with:
9 red, 6 orange, 6 yellow, 7 green, 8 blue, 5 brown, I will proceed as follows:
Eat 1 red, leaving: 8R, 6O, 6Y, 7G, 8Bl, 5Br
Eat 1 red, 1 blue, leaving: 7R, 6O, 6Y, 7G, 7 Bl, 5 Br
Eat 1 red, 1 green, 1 blue, leaving: 6R, 6O, 6Y, 6G, 6 Bl, 5 Br
Eat 1 red, 1 orange, 1yellow, 1 green, 1 blue, leaving: 5 of each.
Then proceed as normal. Eat 1 of each color, in rainbow order, with brown coming last, untill all are gone.
