If we are given too many options we often have trouble deciding. And if the decisions we make are complex we often find that we procrastinate, not wanting to commit to an answer. It may help if we can eliminate the poor options, narrowing things down to what we know will work. The Colour Schemes are a start.
Many design options are not a good idea because the colours will never fit together. We can get a good indication of colours that do fit together by using a colour wheel. This is an old concept, but it remains important because it is so fundamental to how we see and appreciate the world.
A colour wheel has all the basic colours arranges systematically in a circle. The opposite of each colour is positioned on the opposite side of the wheel. We can use this colour wheel tool to choose complementary or matching colour schemes.
