QoS trees colors

RouterOS General
1

I have a question about trees colors (green, yellow, green).
I found in old post that color states are related with limit-at and max-value.

green - a class the actual rate of which is equal or less than limit-at…
yellow - a class the actual rate of which is greater than limit-at and equal or less than max-limit…
red - a class the actual rate of which exceeds max-limit…

I suppose that is not valid in ROS 6.x.
I believe that what is true is (i found it in new posts):

Green: 0-50% of max-limit
Yellow: 51-75% of max-limit
Red: 76-100% of max-limit

Which of above are correct?

That bit vvv
Green: 0-50% of max-limit
Yellow: 51-75% of max-limit
Red: 76-100% of max-limit

today under routeros 6.4x.x this is correct

Green: 0-50% of max-limit
Yellow: 51-75% of max-limit
Red: 76-100% of max-limit

currently
limit-at has nothing to do with queue coloring in winbox

I think so too.
Because in winbox the color changes based on the % of max-limit.
Τhis I have noticed.
