Back in the day when I was excited about all the various colors in which PC comes I ended up with 3 lbs of green in different shades--all in search of the elusive Zombie Green.
Yes, I did find the Z Green but needed to deal with the other 2 lbs of 'less than perfect color' powder.
I finally decided to use nothing but one of the lesser greens (not related to the Lesser Antilles) until I had used it up. Then I could move on to the wonderful reds, blues and a plethora of all sorts of hues by way of mixing the primary colors.
This is taking a great deal of time . . . and would try the patience of Solomon--from Shamrock green I began to see the color as something from the 8th level of Hell . . . and finally it arrived at Bilious Green--a color I can only experience with an empty stomach for fear of losing my lunch should I have feasted beforehand.
So let this be a cautionary tale and learn from my shortcomings: too much of any one thing (color in this case) is a bad, bad thing
