No one has ever said, "I can't color." Everyone can color - just pick up a crayon and fill in the shape.
The same is true for painting and yet so few people, allow themselves the pleasure of painting.
All you need is a mixed media sketch book and some little bottles of acrylic paint. Use the cheap stuff to get started, because you are just playing. Get a pack of assorted brushes and you are ready. Let yourself have fun and experiment. It doesn't matter if it becomes a masterpiece.
There is no right or wrong way to do it. You can throw it away in the end. If you must, make a simple sketch and fill in the shapes with colored paint.
Just do it! It will make you happy! I don't know why, but every time I paint, I smile!
