Let's suppose a thought experiment to help clarify some of my justifications...
1. You are the only person in existence in the material world
2. You do not possess, nor can you possess, a mechanism through which you can 'view' or 'see' the world
3. This material world which you exist in has the same attributes as the one which we exist within currently
______________________________________________________________________________________
4. Do colors exist?
Similarly:
1. No one exists in the material world
2. The material world which exists has the same attributes as the one which we exist within currently
____________________________________________________________________________________
3. Does the material world exist?
