Depending on what color of pearl you add to the color, it will change it , drastically if you add several parts of pearl. if you use white pearl it will turn it more pink, if you add gold pearl it will turn more orange, blue pearl more purple , ect......
PPG has alot of powdered pearls in several colors.

Have them mix a pint in the met.red your are thinking and them have them mix another pint and add how many parts of pearl you want , shake them up then pop the lids and compare them.

When they are mixing the pearl into the pint color make sure they are watching how many parts are added so when they mix your gallon they can formulate how much is needed to achieve the look
with the pint formula.

If they mix it on a touch mix the should be able to print it out on paint can labels.
Make sure you get a break down of the formula as you may need it later on if you need more color mixed, this will help for a good color match .
