Choosing effective colours for data visualization

摘要: We describe a technique for choosing multiple colours use during data visualization. Our goal is systematic method maximizing the total number of available use, while still allowing an observer to rapidly and accurately search display any one given colours. Previous research suggests that we need consider three separate effects colour selection: distance, linear separation, category. simple measuring controlling all these effects. was tested by performing set target identification studies; analysed ability thirty eight observers find in displays contained differently coloured background elements. Results showed our can be used select group will provide good differentiation between elements
