Asking NewRafael about colour

The Abstract digital artist Rafael Rozendall is someone I have greatly admired for some years now his design process and the way he goes about a project is extremely inspiring. His experimentation and use of colour is one of the defining factors to his work being so engaging and interesting. I wanted to ask how it is he comes to the colours he uses and whether he is influenced by anything else in this picking process. What better way to find out than emailing him! Not only did he reply but almost straight away! Contacting professionals  about their design practice is something I had never really done before now and I found it very humbling the fact he responded so quickly. Hopefully I can use all that I have learnt about how NewRafael picks his colours and transfer it into my own work.
