Jelly Bean 4.2.2 Night Clock / Screensaver with customizable colors.
Hours, minutes, the colon separator (:), and am/pm text can all be set to different colors. Dimming is set by swiping up and down. For example, the clock can be set to only show the hour and minute (one of my favorite settings) by turning the alpha of the colon and am/pm text all the way down.
Also, unlike the stock JB Night mode, this app persists when you toggle the screen off/on, just like the functionality in the 4.1.1 night clock.
Ad-supported. I'll be supporting more devices and Android versions soon, and will upload a paid/donate version with many more options. More customizations for this ad-supported version are in the works as well.
