Red sockets: agility + haste/mastery/crit
Yellow sockets: pure haste/mastery/crit
Blue sockets: hit + haste/mastery/crit
What gems to use will vary a lot, and it's not weird to use 5 different kinds of gems in different parts of your gear.
Ideally your stats will look something like this:
haste: 6.5k (softcap)
mastery: 6.6k (just above haste)
crit: 5.5k (rest into crit as long as it stays below mastery)
As you gain better gear, all 3 of your secondary stats should stay very close to each other, with mastery being slightly ahead of the other two.
