Thanks for that. I've nudged the purple/rose boundary in this post to include 59b in purple. In fact, I thought, why not define the boundary as the noble number that is the limit of this fibonacci-like sequence
4\7, 15\26, 19\33, 34\59b, 53\92b, 87\151bb, 140\243bbbb, 227\394bbbbbb, ...
i.e. 691.3671 ¢.
Maybe all colour boundaries can be noble fractions of the octave.
Of course none of the above ETOs beyond 59b will actually have a notation. Too many steps per apotome or limma. But I don't think anyone will care.
Ha! That's a great observation. There are plenty of spare codepoints at the end of the spartan multi-shaft table,It turns out that, if ||( was an actual symbol in Revo, it would complete the matching shaft sequences for the Rose notation: , with being ||(.

so ||( !!( X( and Y( could be added there. If we do, I suggest U+E338 thru U+E33B.
I don't remember why George wanted to leave that gap at U+E31A, U+E31B, but it doesn't seem likely that it was for ||( !!( . If it was for those, it would have made more sense to have gaps at U+E310, U+E311 and U+E32C, U+E32D. And it seems that, if we're keeping the gap at U+E31A, U+E31B then we should keep a corresponding gap an apotome higher, at U+E336, U+E337.
