It's my belief we can at least try to paint out of our comfort zone and try different styles. At the same time, one interest can also be done in different ways (brushed, fingers, sponges, dotting, splashing...).
I started allover with new paint and tried out the colours I like most together. Preferably, 3 black and white included.

Are you able to mix your own colours?

On the other hand, the air can be: white, blue, purple, red, yellow, grey, green (Northern light). the same counts for roofs, water... our brain will recognise it no matter the colour (or you paint how a drug or drug addict or colourblind person or animal sees the world).

Are you out of red or other colours?

I paint out of the tube and mix on the paper or the cardboard I use to cover the table (also very handy for water colour paint).
