What kind of brush would give this?

[Grifter730]

Can someone tell me what kind of brush would give the watercolor effect that can be seen here:

Notice how in the bottom right side, the background colors seem almost like it was a stain. I'm assuming it's some sort of watercolor brush, but does anyone know what brush can create this effect? I really like it. I'm using Painter Classic btw. I suppose I should upgrade to 8, but if this can be done in Classic, let me know please.

That looks like a watercolor or ink wash...I think you migth be able to mimic in classic using one of the wet watercolor brushes.
