Den. Phalaenopsis, ready for repot?

[AngelinaMaria]

Here's a pic of my den phals roots coming out of the bottom of the pot it's in. Should I repot it? If so should I repot it in a clear pot as opposed to a black one like its in now? Do these roots look right? They were kinda dried out when I got it but once I watered it they looked better. Are they supposed to be white or green? Sorry for all the questions, I'm still pretty new to this. Thanks!
