Hello @trueimagine.
First of all, between colours applications, wait for each layer of paint to be well dry, so paint won't merge.
The base is pink watercolour, all other colours are acrylic - all shades of Black are charcoal.

Also, the finish of this artwork has light graduations of saturation added to it with Photoimpact.
Thank for your interest.
Kind regards.

Ps hope this answer your question.
