I use the calendar widget on my wordpress site. It appears that I can choose the color on the calendar for unavailable dates, but cannot choose the color for available dates. I wish I could make the available dates green, and the unavailable grey. The way it is now, there is not enough contrast between the grey unavailable and the default available color so then people inquiring get confused. I could make the unavailable dates red to improve the clarity but my designer partner won't let me because the red is too bright and clashes with the color scheme of our web site.
