Currently the CO2 levels indicated in the CGDN1 CO2 semicircle and bar indicators seem to have a base value of 0.
The base CO2 level of clean fresh air however is around 400 ppm - these days - and cannot get lower no matter what.
So it might be a nice idea to use this 400 ppm base level as the actual base for these graphic indicators, as not to give the impression that a 406 ppm CO2 level, as in the example below, is only in the middle of the green CO2 concentration, when it actually is at the very low end of it.
The suggested value ranges would be
400 to <= 1000 = green
1000 to <= 2000 = orange
and >= 2000 = red
