How do you interpret the nodes of nemnodes.org?

Hi, I am not tech savvy but I am interested in creating a wallet with NEM and have looked at the site Nemnodes.org to track XEM data.

Most of the information is very clear; however I would like to know the significance behind the different node colours surrounding the interactive globe (blue, light blue, orange). I would also like to know the meaning behind the Nodes: __Nodes [XXX] ORANGE and __Nodes [XXX] BLUE.

Any helpful explanation is welcome.
