So they sent 4 free gold dyes to everyone through moogle mail. So that explains where you got your original gold dyes.
And as I stated in the above, you just need a retainer leveled up to 50 and with high ilvl/gathering skill in order to obtain more, though it rather random. You could easily obtain any of the retainer dyes, silver, true black, pure white, pastel pink, purple, green, blue or purple and ofc gold!
