HexaTime is a live wallpaper which displays the current time and simultaneously sets your wallpaper to the corresponding hexadecimal color. In other words, the clock is shown as a hex triplet code, while your background color is gradually adjusted as time passes. This keeps your homescreen feeling fresh with an assortment of unique hues being displayed throughout the 24 hours of the day.
In addition, HexaTime is fully open source. Feel free to contribute to the app if you see room for improvement.
