The Colortune plug is intended for use while the bike is running on its stand. Yellow/orange combustion color means rich, blue like a good stove top flame means correct and bluish white means lean. You observe the color and adjust the idle air screw to obtain the right mix. It is only for the lower RPM range so there is no need to go riding with one installed.
It is just like adjusting your oxy-acetylene torch by color of the flame.

I have used colortune on my MGB and have to say it's a treat!
Surely beats driving up & down & all around thinking "hope I got it right this time..."
