ROB_ Curious about colors of icons--pink and blue

Green arrows mean that you have responded in that particular thread. I think the pink icons are the more active threads.
My favorite is the little blue button next to the title...immediately takes you to the newest post in the thread you're following.

7milelover....hope you don't mind me answering your question....Rob is in a meeting.

When I first posted this question, it appeared pink and had little green arrow on it. Now it is blue
I surely appreciate your answer, .... BNewb.
