Weirdly, this was my favourite colour when I read the book
And since it soesn't show up, heres what they said about it;
Yellow luxin is most often a liquid that releases its energy back into light quickly, allowing its use as a torch or a trigger to ignite flammable materials or explosives. Yellow nourishes other luxins, extending the durability of luxin structures or tools. Like water turning to ice, when yellow is drafted perfectly, it loses its liquidity and becomes the hardest luxin of all. Yellows tend to be clear thinkers, intellect and emotion in perfect balance.
The results from your color matching test have also shown that you are one of the elite, a superchromat. The magic you do will almost never fail. Satrapies will compete to recruit you, and you will have a wide latitude in what work you choose to do once you finish your studies. You can expect your patron to lavish praise and honors on you. As a monochrome, you will master your color, and only have to defer to bichromes and polychromes and, of course, the nobility and the satraps who support us all.
