Colour is a commonly used device in wrestling to portray simple concepts. Colourful usually means face, black usually means heel. Red is a sign of danger, green is Irish, yellow is Hogan, and pink usually means divas (Except Bret which made it cool).
The Attitude Era brought on by the collapse of traditional wrestling images brought with it many changes. The steroid trials of the 1990s obliterated the idea that wrestlers were holier than holy heroes and so wrestling either needed to revolutionise or die.
As a result, Hulk Hogan who asked for you to take your vitamins and say your prayers was now Hollywood Hogan and in it for himself. Shawn Michaels, went from a boyhood dream to a degenerate and even Bret Hart turned heel.
Wrestling no longer relied on simply face/heel relationships. Colour that was used to demonstrate who someone was disappeared and in its place was attitude. Literally. Wrestlers turned up in jeans and black boots to wrestle, the line between face and heel blurred.
And yet the collapse of WCW and the excesses of the WWE, has brought us full circle. Public outcry over a series of events, not least, the deaths of over a hundred wrestlers, has made wrestling seek a much more friendlier place.
The action has lost its edge, wrestlers are softer with even the heels more cartoonish.
Some remnants remain but to a large degree, wrestling is back with its colour. Faces wear colourful attires whilst the heels were black. Its not unlike that old traditional Hollywood where the good wear white hats, and the bad guys wear black.
Colour as a tool of a wrestler's construct is once again at play, and even before we have seen a single move, we can tell who is the good and who is the bad. We see an aura around them that says who they are, what they represent and whether they will win.
Wrestling is full of fruity pebbles, they tell us who is who.
