I don't know. Yellow dye just doesn't cut it for me. It looks yucky I think. Best Dye Mixtures for Gold anyone? I think Gold and White armor will look cool. (yellow makes it looks horrid). Thanks
The color effect of the dyes are different for each type of armor.
The only ways to get a gold look would seem to be Yellow+Silver or Yellow+White, might take you more then one yellow, silver, or white, to get the best combination for your armor, so buy 3 of each and start trying combos. If your short on money, buy the whites last (try yellow+silver combinations and if that doesn't work just buy one white, try that, then two etc. etc.)
