Shadow Prince Malzahar skin, and his passive

Hello, I have a complain about Shadow Prince Malzahar...

After the mages update, malzahar got a rework, and he gains a new passive with purple aura... so far ok for the original skin, but it's not ok for Shadow Prince Malzahar... this skins is yellow and White, I know just a recolor. but when the passive shows up the yellow/White turn into purple just like the original...

look the problem:

My suggestion is: change the color of aura for this skin, form purple to yellow
