To manage your Timesheet settings, navigate to your Timesheet then click the gear icon 
in the top right corner of your Timesheet:
This is where you can set "Work Hours", choose how you want time to round, and choose the color grouping you wish to display your timesheet entries in:
The Color Grouping setting allows you to group by Project (each Project is represented by a different color, so ever Item in the same Project has the same color), Item (each Item is a different color on the Timesheet), Project Work Stage (every entry matches the color of the Work Stage assigned to the Project the time is tracked against), Item Work Stage (every entry matches the color of the Work Stage assigned to the Item the time is tracked against), and None (no color grouping):
Please remember to click "Save" to save your updated settings:
