ColoUR Balance Tool is a color ranking tool based on three criteria: color contrast, subjective data and objective data.
The color contrast was calculated according to recommendations of the WCAG standard.
Subjective and objective data of color sets have been experimentally tested on a group of users. Subjective data are users' preferences for friendliness and visibility of color. Objective data are colors that first drew users' attention. Objective data was obtained by eye-tracking measurement.
