impressive, super original idea. I think from all of the 50+ games that I tried so far, this is the one I could see to become a full commercial game the most. the unique puzzle mechanic based on a already cosy hobby would really fit well with the indie cosy gaming audience. I would suggest to take a look at the game Voxelgram if you want some ideas about scope and progression - it's one of my favourite games and I kept thinking about it while playing.
BUT as charming as your mechanics are right now, I think they would need one more mechanic or rule or limiting element to turn them into a real puzzle that requires some level of thought, because right now it is just busy work and I think even cosy puzzlers want to feel some kind of achievment (at least I do).
You could also reward the player with each weave becoming an image when turned around or link them into some narrative (I feel like your design is hinting at the three Fates weaving the destiny from greek mythology? coulkd be cool).
I hope you don't take me blunt words as insult or as me being preachy, but your game really captured my imagination for all the things this could lead into and I hope sharing these thoughts might be helpful.

Yes, i have a good feeling about the game if it would look nicer... and it would provide a nice "Story", some kind of progression, something where you need to make decisions or figure something out. What is currently there is nice for a gamejam and for toying around, but it would need much more effort to get it to the next level. The reason i made this game was that I had the Obi Rope asset sitting in my library and always wanted to do something with it :-)
I dont think the Subtractive color space, or even introducing the "Art" color space (RBY) would really bring it there. I have some ideas about obstacles (little fire pits that sever the rope) or multistage levels where you unlock something that lets you access another part. But all of that will then require a good ability to create interesting puzzles, and I think I am not that great at it :-) ...
I will want to polish the game a little more, introduce a timer and also finish my idea of a level editor with the ability to share a level text string to others and competing for best time. (the levels can have a JSON and a string representation) But outside of that I would need to have access to a 3D and 2D artist and best also a composer and sound artist to make it good.
