I've been playing around with more abstract stuff lately - I'm doing a series of prints that are basically just weird circles, hence the goofy old timey name of cyclometry :) The colors on this came out really neat in person!
It's actually a plate of titanium I did some patterned anodization on. Anodizing titanium creates a nanometers thick crystalline layer that can constructively/destructively interfere with lightwaves to create color without pigments or dyes. I invented a process to spatially control anodization a few months ago and I've been using to create art ever since. Let me know if you have any other questions!
That is really cool. At first when it scrolled by I thought it was pastels. The contrast between the diamonds and the colours made me take a closer look, and then finding out you invented an anodizing process to make this blew my mind! I look forward to seeing more. Good luck with your patent!
I actually just got the provisional patent filed! I'm going to start working on a breakdown of the process now and throw it up on my website. If you have any questions I'd be happy to answer now though!
