Hi everyone, I did a fair amount of design myself sometime ago and always found the colour wheel a good place to start. If you do a search for the adobe colour wheel you will soon realise that there are certain ways to choose colours based on where they are on the colour wheel. So for instance if you choose a colour you like and then imagine that as one point of an equilateral triangle they other two colours will automatically compliment your starting colour, this is the triad method. The complimentary method are opposite colours on the wheel. Hope this helps you on your colour question.
