Meaning of logos

Can someone tell me what is the meaning of different logos in topic section. Like there is a blue envelope, a red one, a light brown one. Can someone tell me what this means?

Red one is the hit topic. I think when crosses 1000 views or probably number of comments.

Blue one is not a hit yet.

Light brown is an old topic that was a hit.

I guess that's what it is. 🤔

blue one is new topic , when that new topics crosses 1000 plus view it become hot topic red one on same day , then hot topic will become pink shade when a day or two pass , then there are polls , vote up many types of topics
