You might want to double check this, but I'm 99% sure - CE Phenolic is electrical grade canvas reinforced, LE is linen reinforced, XX is paper reinforced. This is the stuff people refer to as micarta. I like CE the best, though LE looks really nice. You're probably only going to find these in black and natural (tan/brown) unless you get some from a special run.
There is also glass reinforced stuff which is not known as micarta such as G10, G11.
All of this stuff is phenolic based. You can also get polyester based stuff, but I would suggest you avoid it if you can, phenolic is better in my opinion.
For special colors, you're going to need to order from a knife supply house. I think Tracy has a good selection. Personally, I just stick to black and tan.
