I believe that if this system is to be implemented, there should be a chess.com vote to decide on which colors corespond to which level of activity.
Feature Request: "Active Players"

Chess.com already makes available a wealth of information about each member. Whenever someone posts in the forums, 7 items of information are displayed about them:
PHOTO / AVATAR |
USER NAME |
LEVEL OF MEMBERSHIP |
LOCATION |
COUNTRY FLAG |
MEMBER SINCE |
MEMBER POINTS |
If members voluntarily adopt some of the proposed protocols, a few more bits can be squeezed in:
TimeZone (http://www.chess.com/forum/view/general/simple-local-time-note)
Essential Chess Type (http://www.chess.com/forum/view/community/its-another-rollover)
Clearly, a member's profile yields a further mine of background 'gen' - including typically their gender and age - especially if the Extended Personal Profile (http://www.chess.com/forum/view/community/who-is-player-x) protocol is followed.
A member's stats show their Rating, Move speed, Timeout%, etc. Their games make explicit their preferred openings, network of regular opponents (who are probably their friends) and so on.
Their forum postings reveal their opinions - and perhaps even their political and religious affiliations.
There is, I would say, a fundamental difference between community-moderated feedback (such as the thumbs up / thumbs down evaluation of posts; or the 'naming and shaming' of 'rude' players) and system-derived labelling such as this colour-coding scheme - which merely condenses already-accessible bits of info from other parts of the site and presents it in a more readily visible form.

Has KevinGabbert's suggestion been given the green light?

If I've red their priorities correctly, I doubt any amount of argyle <><> will get them to move this to the top of the list.

You may well be white.

You may well be white.
The sheer terribleness of these puns just blew me away...

I'm sure if you hit Erik up with a quick yellow he'd azure you that it hasn't fallen off of the list.

Just another variation on the player-speed whining, if you ask me. I tend to come to chess.com at least once per day. I seldom move more than once per day in of my games, and sometimes not even that.
Avg. time/move serves this purpose perfectly well; further development time would be better spent elsewhere.
In keeping with the active theme and colors. Here is a consideration that I use before I challenge a player or accept a challenge. I always look at their page and determine there time outs or vacation time. I do not play players that have any vacation time. The only exception would be when I play tournaments because I do not have control over those who join tournaments unless I am the one setting up the tournament.
I don't follow you. Where do you see someone else's vacation time? Virtually everyone on the site must have vacation time. How do find any opponents?
