Can someone explain to me how the new color system is going to work versus our old gear?

Cause If I find that after the patch my inventory will contain fingerless raptorskin gloves white instead of fingerless raptorskin gloves of slaying I will be very pissed with the people that cried about colors and bs...

I payed nearly 400-600k gil to materia those gloves because they had better stats, don't tell me that I have to buy them and materia them again!
(That is going to translate to millions of gil loss if I add all my materiad gar in all of my classes).

At least ask from the devs for a way to take out the materia and lose the gear instead the materia.
