RJB is for "Rouge - Jaune - Bleu", which is the french for the primary colors : red, yellow and blue.
This series include only theses three colors and a white background.
I first draw a geometrical shape with Photoshop.
Then, I make some sort of matrix or stencil from it and use it to reproduce the shape on the wood panel.
I can reproduce the same shape as many times as I like.
It will be the same shape each time, but never "exactly" the same.
I was inspired by Marcel Duchamp and what he called "inframince" :
The idea of something so less discernible that you have to imagine it to make it exist.
