Not quite. The land ownership layer is not working right now -- giving a service unavailable error.
Color should work, except AZ, as noted in the other thread. Not sure about Mexico -- it should give B/W aerials for Mexico. Does it not?
Land Ownership and Mexico are Custom WMS servers that come pre-programmed, so if you want to turn them on/off you do so in the "Custom WMS Servers" (under the window menu). Color is a special tileset made up of a conglomerate of many servers. It cannot be turned on/off at this time, except for batch downloads.
