All of the stages are very simple.
From a flat colour ‘coloured ground’ (think painting a wall) to a simple pencil line drawing, to the first painting stage using one colour straight from the tube.
This course is all about progress.
Sure, your colours might be a little different, the drawing may go a little out, and the underpainting may be a bit too thin. But these are all very small changes, the principles are still being developed and learnt, so even if you’re going ‘wrong’ you’ll still be developing as a painter.
