I am currently playing The Nexus halls of treomar. but ive run into an issue i cant figure out how to change the colors to the combination red green blue blue orange yellow i know its probably obvious but how do i change them is there a spell ive tried carrying them to the pedestals and ive tried selecting them but nothing happens any help would be appreciated

Well, if I get you right, you tried activating the runes?!
But, in order to open the door, you need to place them on the pedestals, by dropping them off next to the right colour (Shift+LMouse) and then bringing them into position on the pillar. (rune 1 on the red, rune 2 on the green, etc...)
When you're done, the passage should open.
Hope, I could help you
