For this project I wanted to make a comic based diamond Emma, but it's kinda difficult when her skin keeps changing from grey to blue depending on the artist, so I finally went with a blue color scheme, using the following paints:
• Pastel Blue • Sky blue • metallic blue

* The pastel blue as a primer
* The sky blue for a washed layer to highlight the detail in the sculpt
* Apply a layer of glossy resin
* The metallic blue for a washed layer to ad some sparkles

And if you follow the list you should end up with a similar result
