This puzzle was inspired by Paletron's excellent puzzle 'Building Between'. Published here. I have also included links to a colourblind-friendly version of my puzzle using symbols in place of colours. Enjoy!
---
Normal sudoku rules apply.
Draw a line through each set of coloured dots. Each colour has a different line and lines cannot share cells, branch or travel diagonally.
The digit in a dotted cell gives how many of the 8 surrounding cells contain a line.
The lines are all renban lines and must contain a set of non-repeating consecutive digits, in any order.
Some lines can be drawn in more than one way using the digits they cover.

Solution code: Row 8 followed by column 8 (18 digits, no spaces)

Rules clarification. A "line" must have at least 2 cells right? Specifically the purple one

This is one of those puzzles that doesn't quite seem possible at first, but then can slowly be chipped away at for a very satisfying solve!
