Yeah, I've been doing those same morning as compared to middle day tests and coming up with very different colors the past few days. I think as long as a line shows your passing, but I do believe that drawing a correlation between the color density and the amount of metabolites would be pretty legitimate. I've had some "ghost" lines that I believe would test non-negative in a lab too.
I often engage in role playing games or activities in which certain scenarios are played out. To me, this is an RPG, an MMORPG even. No more serious than the characters on World Of Warcraft.
