So for those who might have missed it, as @Tim Smith put it, we had a little surprise in the latest update in the form of flexicolour limestone! This isn't the firs time the devs have been extending upon existing sets ( more mud wall pieces in the Africa Pack; flexicolour for the concrete set), so I decided to open up this topic.
For me personally, I tried to be as modest and conservative as possible, and I decided to restrict myself to the base game sets and the ones I felt are the ones that would benefit from it the most.
For starters, the corrugated plastic roof set. It feels like it was originally intended to be flexicolour, and it seems like the most obvious one to give flexicolour to. It's one of my favorite roof sets to use, and I think adding more color options to it would make it even more useful.
Second one, is the India building set. Now for this one, I decided to split it up a bit. As an MVP, I'd personally think that the basic set and its corresponding construction items (arches, blocks) are enough to make flexicolour, the trims and the murals would just be an added bonus, but I don't consider it to be a must. However, I do think that the texture of that set is extremely good and would benefit immensely from more colour options, as due to it's really bright orange colour it is today limited in what you can use it for. (Yes, I am aware that a mod exists. But I don't like duplicate sets, they just take up space)
Now finally, I'm going for maybe a bit of a controversial pick ( because I know we all would want everything to be flexicolour but I'm trying to limit myself to sets that have a uniform primary colour), but for my last pick I'm going for the thatch roofs. As much as I love the bright colours and I think it works well as freshly thatched roofs, we all know very well that thatch roofs do not stay this vibrant. Slowly, over time, they turn a brownish to even a greyish silver look, and I would love to be able to introduce that to the game. So my last pick goes to the thatch roofs.
So there you have it! These are my three picks for sets I'd like to see as flexicolour in the future, at least for the base game sets. Extras like the dry stone set or the corrugated roof set from the Australia Pack would be extremely nice to have, but in my eyes, these are personally the most essential ones from the base game.
And as a closing here, big props to the entire dev team for expanding on existing sets and bringing new life to them
I really appreciate that!
