Thanks.
I thought it meant something bad

I attached a picture of the tooltip I don't understand. Hope oit helps.
Its the orange box with the blue arrow.

Sorry for the noob question, I searched colony tooltip but didn't find anything. Also didn't find it in the tour or galactopedia or manual.
What does the blue arrow eencircling the orange box mean on the colony tooltip?

Also, where should I look for explanations of these type of things?
Thanks
