It’s not a specific resource, but some things to think about:
The flattened boot image looks a lot like a Native American/First Nations northwest coastal art style called Formline. I don’t know if Pierre Hardy has studied formline or not, but I would suspect yes.
The second pattern is a simplified close-up of a diamond. A Google search for “diamond macro photography” (a word for extreme close-ups) found several similar example photographs to copy and stylize.
While it’s possible to just strike out on your own and try to make new patterns, most people are influenced by things they have already seen, whether they know it or not. If there are specific art or design styles you like, such as Art Deco, Rococo, or spray paint graffiti, or particular artists or designers whose work you are inspired by, I recommend you start there. Also think about themes in natural objects you find beautiful or striking, such as that diamond; browse some macro photography, as most objects start showing patterns when you look very closely.
Look at their stuff. Look at a lot of it. Read resources on how they did that, and copy bits of what they did for practice. Look at the color combinations every time you see something with contrasts you enjoy, and save a copy to figure out what you like about it and how to reproduce that feeling. Start keeping an image library of objects with shapes and colors you like: fur and scales, the curve of a particular sculpture or hat, the angles of trees or ruined buildings.
There are hopefully people here who can recommend specific color theory resources, but I have read some of those resources, and the ones that say “yellow looks brighter next to dark blue” only get me so far. The ones that show examples of art actually embodying the principles gets me closer. But the best for me is looking at stuff I like and thinking about how it matches (or breaks!) the principles I have been reading about… And then trying it for myself.
Good luck finding your style!
