Getting creative with bright colours. Purple and orange being almost contrasting colours on the colour wheel make them a great combination for dramatic effect. Some other less dramatic options in the same colour family could be maroon and gold eye shadows. Lining around the eye with black eye liner is always a good option when using bright colours. This emphasises the eye shape and will give a good background for colours to stand out from.
Part of the reason I started a career in Makeup artistry is because I love to paint with oil paints and acrylic paints and I love working with colour. I felt that makeup artistry was great extension of this, I still love to have play and get really creative when I get the chance (while my 6 month old naps!)
