Here are a couple numbers we have used to paint our stuff.  I personally think it is close.

RED - PPG omni-AE MAE Acrylic Enamel brand code 71973

YELLOW - PPG pmni-AE MAE Acrylic Enamel brand code 3274

I will have to dig a little for the bronze.  That is the hardest to get correct. 

All of these are quality paint and they seem to hold up under the sun!!  Of course, we use hardener and reducers as well.
