Round time using logic and not complex math.

The capabilities of the Color library are limited to pure mathematical manipulation of the colours based on colour theory without reference to colour profiles (such as sRGB or Adobe RGB). For most purposes, when working with the RGB and HSL colours, this won't matter. However, some colour models ...
