By subscribing to the newsletter of Dover publications I have access to free samples of colouring pages. I had printed this one out quite some time ago on copy paper planning to colour it in with my watercolour pencils.
However in the meantime I got hooked on my new liquid watercolours - colorex from Pebeo and Ecoline from Royal Talens. I had used them on watercolour paper only. Well, there's always a "first time", so I unscrewed two bottles: the magenta bottle and the cyan bottle and put a little drop of both of the colours onto my palette. I had the goal to only use these two and was rather excited how many colours you can mix with them!
