20. Exhausting for the eyes Me 
“Bright colors can become tiresome on the eyes and should not be used for large areas of a screen and a
vibrating effect can result from contrasts in brightness being too large or when eyes have difficulty focusing
because of two similarly saturated colors used in combination “ - Stone, Debbie [et al.]. User Interface Design
and Evaluation. Morgan Kaufmann, 2005.
