"The immediate step that needs to be taken is that the clubs take steps to acknowledge the important part that refs play, and that without them they can't have games.
"Clubs need to take a lead," he said, "and sometimes managers need to be a wee bit more responsible."
"In the same way they don't expect perfection from their players they can't expect perfection from match officials.
"I'm certainly not going to criticise Steven Craven for taking his decision because I don't know how much abuse he has had to put up with. I don't know what his family have been subjected to.
Celtic manager Neil Lennon was furious that Dougie McDonald, the referee in the game on 17 October, first awarded a penalty then changed his mind after consulting with his assistant, Craven.
"We need to have as many people as possible coming into it and then you can sort out the good one from the poorer ones.
"Match officials' performances are analysed far more than the players' performances are. We seem to expect match officials to produce perfection in games where we don't expect that of players."
While admitting to being "a little surprised" that Collum had been put in charge of the first Old Firm match of the season, Clark felt that the referee had performed well.
"People are going to look at individual decisions, but over the piece I thought he did well to control a game in which the players did not offer him very much help and which probably threw up more contentious issues than any Old Firm game for quite a long time," he said.
As for the controversial penalty, awarded by Collum when Rangers defender Kirk Broadfoot fell to the ground after glancing the leg of Daniel Majstorovic, Clark said: "I think Willie was caught in the wrong position.
"I'm sure he would acknowledge that himself. He was then in a position where I think he only saw it out the corner of his eye."
