Paint Color Match

[AW]

I am replacing the front bumper cover on my 1990 80Q,  but the used bumper
cover I bought to replace it is slightly different in color from my car.
Given the car's age and mileage, I can't see spending the money on having a
professional shop repaint the cover.  For those of you with bamboo tan
metallic (read gold) cars, have any of you had any luck finding a matching
spray paint?  Thanks in advance for any help.
