I have these two menus on google sheet, and I want to change their colour to red and blue. How can I do that?
function onOpen()
{
var menuItems1 = [{name: "submit new order", functionName: "NewOrder"}];
var menuItems2 = [{name: 'submit order change', functionName: 'OrderChange'}];
SpreadsheetApp.getActiveSpreadsheet().addMenu("submit new order", menuItems1);
SpreadsheetApp.getActiveSpreadsheet().addMenu("submit order change", menuItems2);
}
