How to paint a flat blue sky in Watercolour

How blue is the sky and how blue should you paint it? How can you make it look smooth and not grainy?

Blue watercolour is tricky to handle. Colour straight from the watercolour box never looks natural and is often gritty or grainy because the pigments don’t grind down as small as some other colours.

Beginners always find Blue hard to work with. In this video, I’ll show you how it’s not just the paint – the paper you use has a great effect on your finished picture.

Then there is the technique – if you want smooth flat areas of blue you need to take a bit of time and care. Let me show you how.
