Chromatic gems.

Ok so I have this wand which boosts Fire gems +1.
I read the Chromatic gem I had to change colors. It says Right click gem, then click the hoel you want to change. Well I did this and the Wand changed the opposite hole and now both are green as opposed to the blue that I need.

I'm calling this a technical problem because I believe the instructions are completely opposite as to what your'e supposed to do, unless I'm missing something here. Is there any way to remedy this issue? Or is my wand now garbage? I'd like both sockets blue. Also out of Chromatic gems atm. Please help!

it changes the colors at random, so you never know what you are going to get, its all chance

Each slot can be 3 possible colors,

so a 2 slot has 3x3 = 9 possible permutations.

So every chromatic orb you use, you have a 1 in 9 or 11.11% chance to get the 2 blues that you want.
