Why is Lyse's outfit not dyeable?

[Narthice]

I need this in Lime Green, Had to change my color scheme

I like this jacket so much. I'm hoping that "rework to glamours" also addresses these problems, such as multi-slot color dyeing.
On a side note I can't figure out which boots to glamour on my PLD with it. On bard I'm using the Saurian boots of aiming. but thanks to lovely class restrictions on glamour that's a no no for Tanks
