What should I choose? Watercolour or acrylic paint?

Watercolour paintings can fade over time and generally require glass in a frame to protect the painting as any moisture can reactivate the paint and it can run.  They have a much thinner, transluscent look and the painting and colours can blend and merge well with water added to the paint.  Watercolours can produce a more delicate painting.

Acrylic paintings do not need glass to cover them in a frame. Acrylic is thermoplastic and once dry cannot be made to run with water or moisture. They can have a bolder and more opaque quality on the paper or canvas. Acrylics can be sealed with varnishes to help give them archival quality and can be UV and fade resistant.
