Of course! You can look anyway you want to on cam! This is your show!
Whether or not you should is ultimately up to you. Your clients will give you a good Idea of what they like. If you already have a wild look, with tattoos, piercings and/or bright-colored hair, you can easily pull off wild Makeup for your camshows.
If your look tends to be more natural, you may not want to wear exotic makeup every day. You could save the extreme looks for celebrating holidays or wearing costumes. Not all men like to see women in heavy makeup, so keep that in mind.
