I have just discovered Golden acrylic paints. Well I'd heard of them, but they aren't available here in my neck of the woods so I'd never tried them. However I recently got some from Jackson's and they are da bomb!
They have a wonderful smooth consistency and the colour, oh my, such intense hues, even in the more transparent colours. They are expensive, as is usually the case here in the UK with anything imported, but I've started saving up!
This piece was done largely with Golden paints and a couple of texture gels with lots of layers of glaze to produce the depth of colour.
