If you are in Iron Age and have Architecture unlocked, you can use some Forge Points to invest in the Great Buildings of others; possibly resulting in earning more Forge Points and/or the opportunity to convert the Forge Points into storable forge point packages (as well as extra medals and blueprints).
As far as obtaining Dye as a required goods, you can visit the market and exchange your existing goods with assorted trades.
You will require a Forge Point to conduct a trade (if you are not in a guild).
Look for opportunities to trade any goods you regularly produce for those you currently don't, as they will become useful.
Managing the Market and Great Building donations should help you with your problem.
If you need any help figuring out how to manage the Market or working Great Buildings to convert Forge Points, it is possible others may have better advice than I do.
