Finding the best color palettes is always going to be a useful and important thing to do. The biggest thing to consider when you get involved in design is that you can always find inspiration in color palettes used by other designers. This is going to help you expand your knowledge and it will give you new perspectives.
The best thing about doing this is that you are going to be able to create some amazing looks with your original touch, but a good color palette to use as your starting point is a great advantage to have.
