system management colours problem

I am currently running a Lacie 5Big1 and 5Big2 NAS with FVDW firmware. Installs have been completed with both NAS runnig RAID 5 with static IP's. I would like to configure a different colour scheme for each NAS but after selecting changing colours in setup, colours and then "Save the Console Colours" I refresh but nothing changes. Am I doing something wrong or is there something I haven't done that causes this? Also is there a way we can configure these colour options from a shell CLI?
