Art these days comes in many varieties. Personally I find all of them fascinating and greatly enjoy other peoples art. Even when you personally do not like the art you are viewing, that does not needlessly mean that you have no appreciation for the work that was involved.
Colour is very interesting to me personally as it can change the face of your painting. Creating and actually reflecting the mood you want to portray. It can give a chilled effect, to even searing heat. Colours and music are a wonderful combination!
Spattering is a way of achieving a brushstroke free painting at random, and an on the spur of the moment kind of look. This can be done leaving no brush marks by spattering or actually flicking your paint on to your support. This will leave marks that are dappled, speckled or even mottled.
