Color

I, too, would like to know how to change the color… I just want a medium shade of grey, the red is very bright!

The way I’ve done is this: copying to my CSS style sheet (through my Theme option “Edit CSS”) the following part, from the file ./availability/style.css.
Then I’ve changed background-color, color and text-decoration.

.wp-availability-month table tbody td.wp-availability-booked {
    background-color: green;
    color: white;
    font-weight: bold;
    text-decoration: none;
}

I dont′t know if it’s the most optimum way, but it works ?? Remember to erase the quotes if you copy-paste.
