Color Time is a clock which tells you the time by changing color! It takes the hours, minutes, and seconds of the current time and fills the screen with a hexidecimally-specified web color based on those units (red, green, and blue respectively). For instance, the time 11:40:21 corresponds to the hex value #758A59, based on the proportions of each unit to their respective maximum values. Alternatively, you can choose to have Color Time take the time units as direct input and display the color #114021. Tap on the screen to toggle the digital display. Color Time supports both portrait and landscape orientations, as well as both 12- and 24-hour time. Enjoy!
