"Easy to use but limited functionality"
Very simple to use and find harmony using triad, square, triangle, complement and rectangle. Provides RGB, CMYK, or HTML values which can be saved. Allows lightness and saturation values to be easily changed. Does allow print.
Does not allow uploads or the ability to use colors from existing web page or graphic. Has button to allow color info to be saved to clipboard but it did not work. The File option to open a file is not selectable.
Easy to pick colors quickly using 5 types of harmony but limited functionality beyond that.
The Print option works BUT it prints the Color Calculator screen as you see it on half the page and then fills in color below and above the graphic essentially wasting printer color ink. Might be easier to use Just Color Picker which grabs color from any graphic and can actually save the selected values as a text file.
