Maybe use a compacted version of the colony tile? Most of the information lives in the bottom third of the tile.
Option 1: transform scale them down
sccale(0.6) will make them approximately as wide as the card:

Option 2: Redesign the tiles in more horizontal manner

Option 3: Redesign the tiles in even more horizontal manner combining them in a table:

Option 4: Let them be ¯_(ツ)_/¯
I'm good with option 4 for the current colonies display, but like 3 if it's added to the trade with colony menu item.
@ssimeonoff : is this issue still relevant or could we close it?

We see that Red has traded and has no more trading fleet, while Green and Blue has 1 and 2.
When choosing to play a card, you get a list of possible cards to play and you need to select one.
Thus same logic:
When choosing to trade, to get displayed colonies (as the cards are displayed, not just a plain text list) and then selecting one.
