mellow yellow on Regency Square

today I washed on my first lot of colour. The pale regency yellows and  some purpley blues. It always looks a bit dull at this stage, needs the sky. I have been painting in my conservatory and it is pretty warm in there, so I wont paint the sky until it is cool...or the washes will dry too quickly and it will go all streaky!
I am also looking forward to painting all the colour in the windows...
