Once a lab tech logs into 3DPrinterOS, they should go to the printer tab.
Once there, click on the machine settings button on the tab with the information about the raspberry pi.
Go down to the colors option. Once chosen, a box will appear that says select color with a drop-down box next to it. Click on the drop-down box and a 3x4 grid will appear with different color options.
Select the colour that you want, and then hit the ok button.
