V54 was designed for VC paper and puts out a balanced spectrum .
Filters of any kind only pass light of their own color. They do not create light or change the color of light. The original Aristo tubes were deficient in green used for low contrast vc. Some people used yellow to attenuate the high blue output making the small amount of existing green not be overpowered by the blue thus making them somewhat suitable for VC printing..
Single grade paper is exposed by blue light only and green had no effect on it. The original Aristo worked well for its intended purpose.
In short you need yellow/magenta set or a green/blue set such as Roscoe Gells Roscoe works equally well at 1/10 the cost. . Yellow/Magents sets will equalize exposure of middle grey if you change grades. Since most people first establish a highlight or black and change grades to get the proper contrast, constant exposure does not work. It only works if you work from middle grey.
