Your corporate colours say something about you and your brand. They will appeal (or not) to a particular demographic. Best that demographic be the demographic you’re selling to, not the demographic that you represent. If you’re designing (or redesigning) your web site or business card, it’s worth checking what colours mean.
When we recently redesigned some of my brands we sent the designer’s ideas to people within our client demographic. Each brand uses different colours and has a different look and feel.
