There are kits specifically for this (Laminate flooring repait kit). Basically, you get an array of wax-ish kindof bars, in all different colors. You are supposed to mix and match them to match your laminate. Basically, they feel a bit like candles I guess? Kits come with a melter, you melt colors together, on top of eachother until it maches yout laminate. You finish by lightly sanding it an bam. Best result, you see nothing. (though I needed a test laminate piece, damaged it on purpose and tested it on it to get the right color).

I could link / send pic of the one I bought but 1) not in the US and 2) uhm duno if I can link or add picture?
