What about colored QRTZ crystalls? It is you colored QRTZ with decoration (for example, in yellow), fill up the tank with SLTW, and this crystall will be have same color as decoration.
@Ahpiox(View Post) Nice idea.But i am sure its going to be rejected bcoz generally all the ideas for decorations are rejected. However you can grow qrtz using sltw and then add decorated bizr which will make it decorated.
