We had vinyl shades that were perfectly good but after we repainted our interior of the house, they were absolutely the wrong color. Because it would be thousands of dollors to get new shades we wanted to try to change the color. We got the color chart and found the color that we felt would be right for the job. It was the perfect color and we were able to change the color of the shades to match the paint on the walls. The large shade is the original color and the one on the right is the painted one.
