Would you consider adding a tech trigger for each recipe that works like how you already add the recipe? for the tech icon I think you could just use the resource Icon or add something simple to tell the difference or something if something else is already using that icon in the tech or crafting menu

love the mod, it's always in my mod list when i play :=)

What would be the trigger for these techs? It can’t be the ore being made, because it wouldn’t work if rainbow ore is the only ore on the map.

the trigger could be the mine/pump each individual resource, but for that particular problem if rainbow is the only enabled resource. I think a check for if rainbow ore is the only enabled/present resource, and if that's the case then add the recipes from the string by mining rainbow ore

I'll keep it in mind for when I next work on this mod, but I don't think I'll make this change anytime soon. Unlocking all the recipes at once or unlocking one at a time doesn't really change that much, aside from maybe allowing you to create oil before finding a patch.

The mod is open source of course, so feel free to open a PR on git if this is something you'd really like implemented.

Alright, I thought to at least mention it when I thought about it as it would be a nice addition to the mod progression balance

I might just do that when I have taken a look at the code and made some sense of it. Programming isn't something I know so most of my tweaks comes from Google AI which I know sound and prob are stupid. anyhow keep up the good work :=)
