Colors in the middle is just a gradient between the two extremes, from green to yellow to red. The planet name colours are the tier indicators. Arranged by tier and then alphabetically, keeping T1-3 grouped since you don’t need any protection there. This is mainly to make choosing a planet to stage from easier, most of the time you’re not looking for T4+, and the chart also flows better with no sudden jumps (ok aus servers are a jump) in the middle.
This is just a screenshot of Blinksec Table / Portal Helper you can make a copy of that and arrange to whichever order you want to and make a custom version There’s also a shards/h between planets tab there.
edit: should I make a similar version with the shards/h tab? Ok I’ll make one… I just like data to be up to date and complete
