Use of Color Filter for Vision Sensor

Under R7a color filters are allowable for Light Sensors, is it an option to use color filters for the VEX Vision sensor? A color filter could be employed to assist in the more accurate detection of a single color--i.e. green, orange, etc. This is important given the fact that the flashlight is not compatable with V5.

This would be permissible if the hypothetical filter satisfied all other Robot rules, such as R9:

< R9 > A limited amount of custom plastic is allowed. Robots may use non-shattering plastic from the following list; polycarbonate (Lexan), acetel monopolymer (Delrin), acetal copolymer (Acetron GP), POM (acetal), ABS, PEEK, PET, HDPE, LDPE, Nylon (all grades), Polypropylene, FEP; as cut from a single 12” x 24” sheet up to 0.070” thick.

a. Shattering plastic, such as PMMA (also called Plexiglass, Acrylic, or Perspex), is prohibited.

b. Plastic may be mechanically altered by cutting, drilling, bending etc. It cannot be chemically treated, melted, or cast. Heating polycarbonate to aid in bending is acceptable.
