adjusting air on cooktop

[Bluetick]

Two of the burners on my cooktop have some yellow/orange in the flame. How do I adjust them to get a pure blue flame?

Maybe post model and manufacturer? A lot of us may have different cook top than you.

Did you remove and clean the burner assembly, and remove and clean the orifice below it by soaking in alcohol? (do not poke anything into the orifice!). If I recall the orifice unscrews with a 7mm socket on the Dometic cooktops. Also, an occasional blip here and there of yellow is OK from what I have read.
Verifying system pressure is not a bad idea either although the CT probably has a secondary regulator. System pressure should be no less than 11" of water column with 50% of appliances running, and should not go over about 12" at low draw. It will go higher when everything is off (lockup) but that's OK. (Adjustment should only be made while gas is flowing thru regulator)

It's the basic dometic/attwood three burner on a 2018 Flying Cloud 27FT.

My reasoning for cleaning the burners and orifices and checking pressures is because when everything is in order the air adjustment should not change. The only thing that can change is gas flow and dirt/debris changing the gas and air mixture/flow. Re-adjusting the ratio to compensate for restrictions does not make sense, eliminate the restrictions instead.
