One of my recurring problems in watercolours is the lack of value contrast. So I decided to try a painting with one colour (a mix of indigo and sepia) to force myself to think about value more, rather than pretty colours!
To make it easy on myself, I edited the photo on my iPad to tonal black and white, so I could actually see the values.
I have to say I really enjoyed the process, and I am thrilled with the result. Let's see now if I can reproduce this in full colour!!
