Issue with coloring is how the game treats the color of your char. You have a default color and then can set that to be different in the console. Especially useful in multiplayer to look different than each other. A glow type might work if its a separate thing that followed you around. Saw issues that people had where they had a similar deal for a shield and it pulsed at their feet but would lag and be off-center of the character at times. Also could add to game lag Id guess with more things being animated.
