The effect of icon color gradient features on users' visual search efficiency.

This study explored the influence of different colour gradients and colour area icons on user visual efficiency through a visual search task experiment with 35 participants involved. The results showed that the colour gradient slope and colour area of the icon significantly affected the visual search efficiency. Icons with high colour gradient slope had the highest search accuracy and shortest search time, whereas icons with low- and medium-slope differed only in search time.
