There are three color parameters in the settings of the rule of work:
- Color of available time
- Color of partially reserved time
- Color of fully reserved time
Select a сolor of partially reserved time to be closer to the color of available time.
As a result, if there is at least one place left, the time bar will not look like it is fully reserved.
In the picture, there is 1 place left in the interval from 5:00 AM to 10:00 AM.
And there are no places left in the interval from 10:00 AM to 1:00 PM.
If you do not want to indicate partially reserved time, then choose its color to be the same as the color of available time.
