Violet doesn’t evoke the wide range of emotions and feelings that most of the other colors do. The purple color range is typically only used as a royal color that is associated with wealth, prosperity or to reflect a rich sophistication. The best example I can show is Crown Royal scotch. Not only do they use ‘royal’ in the name of their premium product, they wrap the bottle in a violet sack.
Oddly enough, the other place you will see an overwhelming amount of purple is in the toys of little girls. Little girls love all shades of purple, so they will use everything from violet to pink when advertising and packaging toys for little girls.
As always, keep in mind the natural emotions that the colors you design with evoke. You don’t ever want a red dominant color scheme when you design a website for a lawn care company. It is far easier to play to the emotions you want by changing your color scheme.
