Dissociate_L-System Patterns_by colors ?

Hi

I am trying to figure out how L-System works with Turtle #Rabbit

Well I need to visualize each pattern, as it is the same pattern each time but in

a different direction,

I thought it would be interesting to add color for each pattern.

Two colors are enough to see where the pattern ends and where the new pattern begins.

I did manually, for each branch I put a custom preview,

as the number of lines is clear I thought I could assign the two colors in a more sophisticated way directly to the SUBLIST output.

I tried gradient map and didn't work as I saw in many posts here on the forum.

I don't get each pattern one color.

Thank in advance for the participants on this forum and for their help
