Matching PLane Plastic Paint Color

[netsurfr]

I have to replace the overhead vent fan in my Dakota and although I have the replacement part I'm now dealing with figuring out how to match the color in the rest of the plastic. I take it I can't just go to Home Depot and ask them to match the color as I'm assuming I need special paint on the interior plastic parts? Aircraft Sprice has something called SEM but the color chart for that paint does not have something that matches (Light Gray) so could use help/tips as to how I could match it vs. having to paint all the interior plastics.

Thanks!
