Is it illegal to use coloured tape on Car?

Is it illegal to use coloured tape on your fog lights in Ontario? I drive a Ford focus and take transparent blue tape and cover my fog lights rather than my headlights. I understand I'm more likely to be pulled over for drawing attention to myself but don't want to deal with a ticket. Would tape on your fog lights be an "illegal mod?" Thanks in advance!

They can't be blue.

If you had an accident, your insurance might not cover you with modifications to your lights, either. It's not safe at all.

I'm on the canadian site…
