No, my friend, in my country (Cuba) there isn't a single store that sells art supplies. Some individuals sell a tube of a color. When you buy something from someone, it's the color they have at the moment because it's leftover from a project. And a simple 22 ml jar of a color can cost the same as a worker's salary. I paint thanks to @wakeupkitty.
I've always written, I like all art, and I've always liked painting.
