Essential colour checklists for Web design

  • Main ingredient for legibility is contrast. You can test your legibility by converting your site to monochrome. Use strong contrast between the background color and the text color.
  • If you need to show pattern, place it in the center because our eyes work harder to take in patterns on the periphary.
  • Important information to the user does not reply on colour alone.
  • Avoid using too many colours at the same time, it creates a confusing overall effect.
  • Black text on white background is best.
  • Red and green are best used in the centre of the screen and black, white, yellow and blue are best used on the periphary
  • Brighter colours are better by interfaces that will be viewed for a long period of time or if designed for older users.
  • If you want colours to be easily distinguished from each other, use darker shades of blue, red, and purple and paler shades of green, yellow and orange.
  • Colours do not the mean the same thing to different people.
  • To convey low prices use brighter colours such a yellow
  • Beige, blue, burgundy, and dark green give impression of high quality, solidity and tradition.
