Colorado still has a slim chance of making the playoffs, but will most likely be eliminated quickly. In order for them to make the playoffs, there needs to be some very precise* circumstances that play out for them, most of which will...not happen.
Starting with the first one: Colorado needs to claim 33 or their available 34 points. That means they would need to win 16 games over the course of the next 17, and only lose 1 game MAX, and in OT or Shoutout. Now for the rundown:
Colorado needs to beat St. Louis in their 3 remaining games. Losing in any fashion to St. Louis would give the Blues too many points on Colorado to pass them.
If Colorado wins all 17 games, they can come in any fashion. However, if Colorado drops a point to OT or SO, then 14 of their wins need to come in Regulation or Overtime.
Vancouver needs to beat St. Louis and LA. Vancouver also needs to collect no more than 5 points otherwise.
Winnipeg needs to beat LA and St. Louis. Winnipeg also needs to collect no more than 3 points otherwise.
LA needs to beat St. Louis. LA also needs to collect no more than 3 points otherwise.
Arizona needs to beat St. Louis in their 3 remaining match-ups. Arizona also needs to collect no more than 14 points otherwise.
Dallas has no game-implications that would affect Colorado making the playoffs. However, Dallas does need to collect no more than 9 points over the remainder of their season.
St. Louis can only collect 2 more points in any fashion, EXCEPT for a win over Colorado.
The Vancouver/Winnipeg game has no implications on Colorado making the playoffs.
Given these scenarios:
Colorado will make the playoffs with 73 points St. Louis will miss the playoffs with 71 points LA will miss the playoffs with 70 points Winnipeg will miss the playoffs with 72, 71, or 70 points Vancouver will miss the playoffs with 70, 69, or 68 points.
Colorado can still lose 2 points, given they win no more than 3 games in Shootout.
