Possible bug with Cruadin weapon glow

Not sure if this is a bug or intended feature for the DRK weapon Cruadin, so I thought I'd post it anyway to be safe.

Date & Time: Unknown
Frequency: Always
World name: Cactuar
Character name: Baraitar Nazzlohsyn

Summary:
When drawn, the Cruadin weapon displays a glowing effect for the green (small, minty-green) part of the weapon, but also causes the brown (hilt) section of the weapon to glow as well. The glow for the brown portion of the weapon is only really visible at night or in the dark. I believe the weapon was only intended to glow on the green portion of the weapon, and that the brown parts glowing is likely unintended (as it doesn't look natural).

Some screenshots of how the weapon glows in the dark (the small, bright part mostly hidden on the other side is what I'm calling "green"; the rest that isn't the blade or flowers is what I'm calling "brown"):

Similar weapons like the Narval don't appear to glow at the hilt like the Cruadin does:
