After almost 300 days playing I have come to a simple conclusion for the betterment of this game and that is establishing colors roles and fixing current color issues.
First and foremost, for any begnining player, they assume the first cover is the strongest color, as we all know this is not true, so D3 please fix this.
Now for the meat of the subject, defining colors. I think choosing to define roles of certain colors would do amazing things for this game but you have to set rules.
Rule 1: Each color should be able to do at least one thing that only it’s color can do
Rule 2: Colors can share similar skills, but one color should be able to do it better than the others
Rule 3: Have colors with opposites to promote strategy, example black is purple’s opposite in what they can do
Rule 4: Have colors having allied colors to promote strategy, example red and green both like to do damage.
I can go on but these 4 would start us off nicely So what do we know about our colors right now?
These are 3* and 4* only

There are other categories one can break things up into but there does appear to be a little bit of a pattern.
All colors can do damage but red, green, and black are the primary colors and of those 3 green has a higher number that damage all.
Your primary defenssive colors are yellow, blue and purple and so on and so forth so here’s what I have determined
Does large amounts of damage, both direct and team. These seem to be higher costed but bigger damage
Does lots of damage, in fact does nothing else but damage, they seem to be lower costed than green and don’t always do as much damage, tends to be more direct
A little bit all over the place right now, but it does do damage, not as strong as red and green, but it has it’s moments, this color is the master of attack tiles
This likes to create protect tiles and stun, not much for damage, it also likes to slow the game down via AP steal as well
The least represented, specializes in AP steal, defensive tiles, has only one damaging skill and it’s a whale of a good time 
The color that’s the most all over the place, it does it all, it does seem to be the best color for healing and creating specialized tiles, but also has some offensive power
I think D3 needs to tighten up on the colors, and more recently they have. Some characters I need to have their colors adjusted like The Hood, his blue should be purple. She-Hulk’s blue should be purple, her green should be blue, red could be left as is or switched to green.
Irregardless, having a set of skills specific to a color would go a long way for this game, as well as adjust cover order to bring a smart and coheisive architype that makes sense and also easier for newer players to understand. A new player sees Spiderman and thinks yellow is his stongest, than blue than purple, except it’s not, these are the little things that need to be fixed.
