There is an amazing array of paint mediums out there.. There is oil, acrylic, and watercolor, but even those have a wide array of of mediums and formulas they come in. I am most familiar with watercolors. For me they are the most rewarding and enjoyable to work with. Another creative person may find them to be the bane of their existence. It makes neither of us right nor wrong, it is reflection of our talents, our interests and our personality. It is one of those sort of crazy wonder things about paint. There is a kind and a color for everyone.
