favorite Pantone Colors for Products

Hi,

I always have trouble picking the righ tcolors from a Pantone book.
What are popular PMS#'s you like and use often for high tech products.

Black:
Blue:
Silver:
Off-white:
Dark Gray:

It always looks good as a chip but so different as plastic or paint.

Anyone got some numbers they like to use often?

They sell pantone paint at home depot
