If you look at the class chart shown on the diep.io wiki, you'll see there seems to be a color coding scheme using yellow, blue, red, and green, but there's no key. Can anyone explain what the different colors indicate?

Not definitive, but as mentioned on the wiki
Interestingly, there is a recurring pattern of colors in the upgrade selection menu and the Class Tree. The first tank will always have a light blue background. The second will be green. The third will be red. The fourth will be yellow. The fifth will be dark blue, and the sixth will be purple (This order can be found in tank's add stats buttons which are color-reversed). Regardless of speculation, colors do not seem to represent anything other than a simple order pattern to more easily discern tanks apart when quickly selecting an upgrade
Note that Tank->Twin is light blue, and adds an forward extra barrel, while Machine Gun->Gunner has a similar effect, but in a different color.
It is interesting that tanks which appear in multiple paths (Twin Flank and Quad Tank) have the same color both times, but they have been placed in the same order to keep the pattern.
Image below for observing the tank pattern.
Actually there is a key but never added
It's now shown as [1], [2]
If you click 1 or any other numbers then you upgrade for it. You can use E to auto shoot too and C to autospin
If you want to know how to calculate those upgrade abilities then look up on their reddit.
nothing, they are just for decoration.
1I think it's just to recommend a tank class in a list.
- Purple - Unique, Extremely Good (With High Skill)...Factory has drones with bullets. It's unique and has gotten to first place multiple times.
- Dark Blue - Rare, Very Good (With High Skill)...Battleship, Auto-Trapper, and Smasher have easily gotten on the scoreboard many times. They are a little hard to control though and require skill.
- Red - High In Value, Great (With Skill)...Examples such as the Machine Gun, Manager, Spike, and Over Trapper have high defense and attack
These are the best class colors
It's a class specialization and bonus.
- Yellow is Bullet Penetration
- Red is Bullet Damage
- Green is Reload
- Blue is Movement Speed
When you upgrade to specific class you get some bonus to this characteristics along with some negative effects.
