Finally, an antidote to the sad beige life. Lots of colour pictures mixed with a bit of history, some colour psychology, instruction, and a lot of personal philosophy. I will say at the beginning it says to ignore the rules and follow your heart, but also has some typical designer rules throughout (cooler paint tones in warm rooms and vice versa, keep undertones in mind to match different colours, odd number of items is best etc. )
A good jumping off point.
