Am I tuned right?

Am I tuned right?
I read somewhere that your jets are set properly if your exhaust pipe (Yoshi stainless) turns a nice gold color. It said if it turns blue it is too lean and if it glows it is extremely lean. Well after jetting, the pipe turned a beautiful gold color, but the first three inches or so of the left pipe coming out of the motor is blue. And after riding for a couple hours yesterday a little bit of blue here and there is showing up, but just barely.
Am I okay or do I need to go up a size on jets. I'm running 146 & 148 with no lid at an altitude of between 4000 and 5000 feet (Dyno jet recomended 144 & 146, but that wasn't considering no lid so I went up a step on each). Both screws are out 3 full turns. It rides awesome, the only thing I noticed was that after is was warmed up I had to give it a touch of throttle in order to start it, but other than that it seems perfect.

When you say jet up, do you mean larger size jets? My understanding was that a higher altitude requires lower size jets. The air is thinner the higher you go, so you can't put as much gas to mix in with the "lite" air. I don't think I need lower size jets, if anything I think a step up, but I don't want to change it since it is running fine now, unless others think it would benefit my Raptor.

I found my pipe glows red, specifically on muddy mx tracks.
My plug is a little dark, can I lean it out with the mix screw and avoid having to rejet? It runs fine for me, I just rev the pi$$ out of it. But I let my buddy run it yesterday and he was easy on it because he hasn't ridden a quad in a while. When I jumped on, it was bogging a little, until I pegged it and cleared it out. Reminded me of my old two-stroke.
