Oh. Are the textures already decided?
Would it be a problem if I sent them over as they are?
Yeah, they are. Here are the exact colors of the metals (adding this to the OP also):
80 75 63 255 (Surtra)
222 204 143 255 (Calcite)
249 176 249 255 (Nithlite)
142 7 7 255 (Sanguite)
138 129 111 255 (Sinnite)
235 140 255 200 (Crystal)
It's not a huge problem if they're set up to use colorshifting, as the only difference is that it makes the inventory icons look a bit worse. This isn't actually true, nevermind about colorshifting vs not colorshifting, it doesn't make any difference
