Endpoint allows to create new position for the company.
While creating a new position, an admin is allowed to select a default color for that position. The default color is used when creating shifts for that particular position. For example, if the default color for the position "Store Manager" is green, then when a shift is created for the Store Manager, the color will default to green (of course, the shift color can be edited, if needed).
Position color need to be one of listed colors in params.
