Craft Acrylic paint: colors required, black & white if you are wanting something close to what is shown I have used a Metallic Purple Pearl by Deco art and then a lighter  purple. along with 2 diffrent sades of greens. But you only need black,white, darker purple and a bit darker green. We can lighten these up with the use of your white paint.
