/*
* We want the color chip to have a nice gradient using
* the color of the calendar. To do this we use a GradientDrawable.
* The color supplied has an alpha of FF so we first do:
* color & 0x00FFFFFF
* to clear the alpha. Then we add our alpha to it.
* We use 3 colors to get a step effect where it starts off very
* light and quickly becomes dark and then a slow transition to
* be even darker.
