I have used Touch Up Direct - Tesla white (paint code PPSW), i.e. Shasta White Pearl Tricoat is a good match for factory finish. Paint thickness on car is egg shell thin. The touch up kit includes primer, base coat, mid-coat and clear coat. TouchUpDirect has videos. In my experience when you are done with the touch up the thickness of these layers ends up being thicker than the factory finish.
Consider using Dr. Colorchip's touch up kit as Dr. Colorchip has a paint blending compound that makes it easy to fill in just the right amount of paint, wipe off excess. Dr. Colorchip has videos.
