If you are a web designer, web developer, creative artist, or just someone who creates presentations, you most likely need to use exact and consistent colors. In software and on the web, colors are defined by either an RGB value or a hexadecimal value. For example, African Violet is #B284BE in hexadecimal and 178,132,190 in RGB.
A handy tool to use for this is colorpicker.com. You can search in Google or Bing for "colorpicker <color name>" and the search result will return the colorpicker.com URL or you can use the color chart or you can play with the color scheme generator. Whichever method you use, this is a handy tool. Enjoy!
