Rustycoon,
I have normal color vision but I have administered both the ground and flight test as an ASI. I am curious as to how you complied with the limitation while flying Part 135. Did you always operate out of non-towered airports? If you did operate out of Class-D towered airports, How did you “guarantee” that you would not lose your VHF communications capability during daylight hours?
I would suggest trying to request a “Special Medical Flight Test” through your AME and see if you can get that limitation removed. An ASI would go up with you in an airplane and ask you to identify some light gun signals from the tower and also see if you correctly identify aviation red and green lights, signs and markings. The ASI may also ask you to identify various colors of features on the VFR and IFR charts. Good luck and keep us posted!
