Color Veil

At-will, swift, ranged, wall 1/level, concentration; a wall of chosen color blocks effects specific to the chosen color (see Color): Red blocks physical matter and forces; Blue blocks charges and movement, hardening against intrusion; Cyan blocks psychic phenomena and mental effects; Magenta blocks teleportation across it; White blocks spells; Black blocks negative energy; and so on. Effects of the matching aspect that would cross the wall fail; all else passes freely.
