According to MN, your 'user feedback' or surveys or something says people want colour changes?
Would it he helpful to MN to publish results and resultant plans so we, and you, don't get blindsided.
Eg
Our survey said 80% of 20000 respondents found colours too dull, so we are going to brighten them.
Our survey said users 20% of 200 couldn't identify the OPs posts, so we are going to put a bubble over them (despite posts already being highlighted by colour).
I think it would be helpful to know what feedback you are using to make these decisions. Sometimes it feels like a couple of people asked for it, and your coders thought it would be fun to do, so they did it.
People don't like unnecessary change. But they like options and helpful changes, such as tailoring our colours or see all by op, or edit features
