Iroshizuku collection

Finally finished the collection! My first taste of iroshizuku was tsuyu-kusa, which was a lovely blue I found at a local shop in Vancouver. I liked it very much, and decided to research the other colors. Not only did I discover that the one I bought was a discontinued color, but there were other discontinued colors as well as a limited edition set. For whatever reason I decided then that my mission was to acquire a bottle of every single color. A year later and the set is now complete, can't wait to try them out!

The other section of the display has vacant slots for now, would anyone have any suggestions for what inks to put?
