What color dye would I use to make something match the somewhat subdued yellowish of the 'Temple'/lv 45 monk artifact gear? There's so many colors to choose from

Also, to show how noob I am at glamouring, I don't even know the answer to this:

So I want to dye an item and glamour it as well. do I dye the visual item I glamour on, or do I dye the base item I will glamour over?
