Would be very helpful to assign Clients/Builders a color so that they are easily identified on the schedule, instead of having to pick a color every time. See image for options.
For Clients/Builders who have multiple projects, you could then assign a project as an additional color (options 1 & 3). Maybe it even won't allow you to use the same color for a client/builder or project if that color is already in use with an active job.
*Option #4 in the attached image is the one that our team agrees would be the best. It is a subtle but noticeable way to see the Client/Builder (Gold color in the upper corner) and the project associated with them (the main color of the tile).
**Also having the option to change and set a default color of service calls so that when you view them along with the projects they are easily differentiated.
