Controlling the color on appointment embedded code/widget

[shawnDino]

Is it possible to use a color from your own branding in a services appointment booking embedded code or widget?

I am also really confused as to why the service library prompts for a photo which it then never displays.

I'd like to replace this  Book Online (dinosaurmountainhomeservices.com) I'm trialing square in the hope that its better than godaddy appointments, which uses our brand color and displays photos, but has lots of other limitations.
