Calendar on pages for guest to see prices shows holidays darker -
I want to remove color because it looks like dates are blocked
You can set the color of the holiday shading in the settings for the widget, under Settings > Widgets. One of the options is no shading.
Holidays still shaded on public view of page for selecting dates to send inquiry --
which makes them look blocked
so they will not send inquiry
If you've got a hosted website, that has its own widgets -- you need to make the adjustments by going to edit that particular page on the hosted website and update the holiday color on those widgets.
