Illegal Color Parking Lights In Ontario?

Im looking to change the color of my parking lights in my 2009 Kia Rio to green. now ive seen blue parking lights on other rios. ive heard some colors are illegal and im just wondering what colors are and arent illegal. My parking lights are found in the headlamp unit ontop of the headlight. They do not interfere with my daytime lights not are on with my daytimes.
