Some of the post counts I’m seeing are in orange while others aren’t. Is there a reason for that? See the below screen shot for an example. Does it relate to how recently the last post was made?
I searched on Meta and it seems that:
“Post count should have heat colors applied based on like ratios”
I couldn’t find any more detailed explanations than that.
That’s kind of cryptic. 
Thanks for checking.
Mine have always been orange from day one . Assumed it was an identification thing .
