Hotspot colours

[ggp]

This may be the stupidiest question asked yet, but when making my hotspots, how do i do them in different colours to enable me to have different hotspots ? I can't see how to change it off of blue!

There are up and down arrows next to the block indicating the color of the currently selected hotspot. You can see the hotspot 1 gray out in the room view when you change the hotspot.
