Skyview - row colors in aircraft table

Hello all,

i did not find an answer so far, but why are some rows having a different background color?
There is light blue, a darker blue and a light yellow.

The only i understand is grey for the currently selected aircraft

Thanks

Scroll all the way down in the list for the legend.

OMG

How stupid I am… never went down to the end of the list…
Thanks and sorry. Maybe it’s simply too hot at the moment.
