I made this.
(ignore the blue line at the top)
Changes...
The G for global is now a dark blue.
the color for names is a dark green for citizens, light green for staff (just names)
ALL colons separating the name from the chat have been turned to white
Exclusive and elite tag colors have changed.
Supreme stays the same as before, with a darker tag and lighter chat color
Ultimate is basically current super, much much more appealing.
All staff members have a red rank tag, which further separates from chat and helps them stand out better to citizens.
Helpers have green, mods have yellow, supers have orange, admins, onis, and owner have red colored chat. These are warmer colors and can be looked better to, because of the theme, and also stands out more vs. a citizen color.
Edit: added in server adverts. Pink name like supreme, but gray text.

It took a while, but I recreated what the chatlog formats would look like for each rank since the forums colored chat unfortunately just doesn't properly match what it looks like in the game. The following is what each standard player rank would look like:

In an extremely odd regular day, this is what the chatlog might look like if I was on a political rampage:

Based off of the suggested chat, my personal suggestions are:
- Change the "official meeper" messages to gray - they clutter the chatlog with yellow and make it harder to read the yellow staff member chat.
- Highlight the ClearLag warnings of some sort. Changing the "Warning" label or the number of seconds left to red/dark_red would help players to see this message and avoid dropping items, even if the red color was only on the 20 seconds warning.
- Change the standard Meep-Shouts to gray. This will further reduce the clutter of yellow in the chatlog which will make staff member messages much more noticeable; this will be especially necessary if Mod chat will be changed to yellow.
- Use the first color method. In my opinion, a yellow rank tag combined with a yellow chatlog text color simply doesn't look well combined.
If said suggestions were to be applied, the chatlog would look like this:

[EDIT 1] Edited as to make the multi-line player text indented as it normally is on Meepcraft (when it works) :p

I actually would like to see either of these. I really like the idea of Staff to have warm colors, and Ult to get sky blue, some people don't even like orange(I am one). But hey, its sky blue, and Ult has /fly, and you can fly into the sky...
And Elite's DON'T need chat color. There are like hundreds of Elites, if they all would talk the chat would drown in that chat color. Besides, its only 80$, its interesting how Ranks which are +100$ has colored chat(Except Staff ranks, they are free but still very important, and you can't become Staff member just like that), so it would make no sense for Elite to get colored chat. They already have OP amount of perks...
