Does anyone know where I could find the paint codes for interior trim pieces? (i.e window switches and centre console)

this would be a great help for me to guys!

Good question!
I am gathering that you should write down your VIN and chassis number and ask mitsubishi as i have never been able to match it either.
Its a black slightly greyed metallic bascoat as a semi gloss finish,the best way to achieve this is to simply put a cap full of hardner in the basecoat mix you make if you match it to give the semi gloss finish.
