Protecting the white of the paper
In transparent watercolor, keeping the white of the paper pristine is a major goal. Because white paints are rarely used, sparing the white of the paper and using very light-value colors are the way both white and light are best expressed.
avoid the white/light areas by painting around them
using artists tape for straight lines
using frisket, masking fluid or wax resist to protect any shape you want
black - the banned color
avoid muddy darks. Clear, transparent, non-muddy darks are essential to a good painting. If you need to go darker, use colors that are the darkest values of their particular hue or color.
