The Blue is a half hour from my doorstep. I fish here a lot, in the winter especially. It's a great place to get your sight fishing on! Light tippet and long leaders help here. Small indicators are best, not to spook the fish. I almost always nymph here. Short line high sticking is very effective here. I prefer to fish the section from Chipotle upstream. Sometimes I make it all the way to the dam. I'm looking for fish and movement. If I don't see a fish, I'm moving on. Unless there is a lot of pressure, I'm usually on the move. A few great ways to increase your ability to sight fish is to wear polarized sunglasses and when you release a fish, watch him until you can't see him anymore. This will train your eyes to spot fish and movement! A dry dropper rig can be very effective when the fish are eating off the top. Some dry flies to try are Griffith's Gnats, Parachute Adams, and Stimulators. Sizes 16-20 should work. Some nymphs and emergers to try would be BHFB Pheasant Tails, RSII's, Juju Baetis, Miracle Midge, and various BWO patterns. Sizes 18-22. Some good colors to try are white, olive, and red. Good luck!
