What do the different colors of the counter of replies in the forum mean? green brown red

It’s a very stupid question but I’m really curious to understand what the different colors in the count of replies mean (green, red, brown)

Thanks in advance guys

I can only presume as number of replies increases the color changes from green => red => brown, or some steps of color.

You’ll notice only posts with 0-10 comments are green, 20- 30 look reddish, 50+ brownish.

Edit: I was a bit off, this forum runs on something called Discourse and the color behavior is from a “Heat Meter” effect — basically there’s some relation to views, likes & replies that indicate how “Hot” or interesting something is.

Grayish = Boring
More colored, orange or redder = Hot topic
