Agree with Grafta, if there are things holding you back, work on those before you worry about the colour runs you're doing. Once you're technique is dialed you won't even look at trail maps or run designations again!
Lessons are your friend. Bending knees is your friend. Work on carving and being REALLY comfortable on blues before you head for steeper stuff. Heelsliding down steep terrain should be an evacuation procedure, not a method of boarding down the hill!
