With Quark's beacon redirection, the particle effects keep going up and do not follow the redirected path. I know that another mod also does this but havent tested, CERBON's Better Beacons, also tinted glass does not change the alpha of the beacon particles.

Also I don't know how important it is, but the particles only change color with 2 blocks (modded and non modded) but change with one corundom cluster.
