The yellowness is confusing. Maybe it is my unallocated skill points?
Update: It is. I am so fancy.
I only noticed because my skill queue ran out.
I went almost thirty seconds with an empty queue! Oh well! And there I am finishing off T3 skills. I hate T3s and they are on my list of things I won't ever fly again.
89,921,079 skill points so far. Almost at ninety. A bit closer to 100,000. Why? I dunno. But it seems to be a thing.
