A quality changing tool made with various flowers, once applied to a tome it would add a special quality that changes the color of all runes created by the user to the ink's color. The color of the ink would depend on the recipe selected.

High level, or just runes in general tend to look like a mess with all those colors clashing, this would help remedy that a little bit and make em' look nicer overall.

I'm sorry if something like that already exists and I just haven't seen it.
