Aiming at the problem that current mainstream color pickers do not have a friendly color selection interaction mode for touch screen

which makes the interactive advantage of the touch screen difficult to play.The traditional color selection interaction scheme is optimized and upgraded based on the touch screen

and four new interaction schemes are designed and compared with the traditional interaction mode.The experimental results show that the color selection accuracy can be improved by 6 %～26 % in quantitative time.The optimized color picker interaction scheme can provide users with more choices and provide a theoretical basis for design of future touch screen-based color picker scheme.
