Blue fades quickly but looks really cool. I would go with pink because once pink fades it will just look lighter and not look gross and green if you were to dye your hair blue. If you don' like pink go with purple because purple metallic has a nice look.
How they stroke there paintbrush and how light and dark the color is or how thick it looks and how realistic it is and mostly what is the main reason or a hidden message about the painting.
