Change sheet tab color based on variable

Hi! I really need help with changing a worksheet tab color based on a specific variable inside my worksheet. I have attached the workbook. In this workbook, There is a summary page for all open and closed projects. Between these 2 sheets are individual project sheet tabs for each individual project. i would like to be able to automatically change the tab color (light brown color) for each individual project based on row 3, column C , when "Closed" is chosen from the drop down list. I have a "project template" that is used for new projects, but would like this function to be in the already existing projects (263344, 261089, 11-422, etc....).

Any help would be greatly appreciated!
Thank you!
