You might need to call around. But a lot of O'Reillys Auto parts now have a paint spectrum machine, they can scan a paint chip of your bike/paint.
They then can match your paint, color, metallic, Pearl's, even down to the environmental fade in the paint from over time. They then will mix the paint & put it in a aerosol can. You got to buy a minimum of 6 cans. Also most paint & body shops have a paint spectrum analyzer.
