To celebrate the 64 colors of the new Pebble Time display, here's a simple colorful watchface using 60 of them (excluding black, white and gray).

Hint for reading the time: sharpest contrast (yellow to dark blue) represents the hands. To see it more easily, slightly squint, this reduces color vision and enhances visible luminosity contrast.

This watchface shows time and date (as too many standard watchfaces don't show the date), and reuses the wandering seconds dot from the my "Ziit" watchface
