Copper for air compressor lines

Looking to plumb my garage for air tools. I know I read the family handyman article about this a few years ago but cant remember.

There are 2 thicknesses of copper red/blue?

Which one is thicker for use with 90 psi air tools?

Type L = Blue Stripe
Type M = Red Stripe

For the pressure you are looking at, either will work, but I'd go with K (Green Stripe) just common rigid tubing.
90 PSI is not high pressure in this application.

Hope this helps. More questions, ask and someone will answer you.
