Hi Dear,
I try to add some color to checkbox custom fields, 'cause it could be useful for our business to have color for group of elements in checkbox.
I tested and see that all seems to work well (email to user, email to admin, back end subscription...)
But I write you to be sure that from you side, the styling should not be a problem. (maybe in some parts of the components that I didn't check, as database table and so on...).
