You might want to try GhGL Shader…

thank you for the suggestion but I think there are still missing something.

In the image, shorter line should be all blue. and i am also thinking is that possible to make the colour are apply on the curve but not the point on the curve.

That could be easily achieved by flattening the “N” input of Boundscomponent…

it works!! thank you so much. But there want to ask is that any difference if I flattening the ‘N’ input and flattening the “Z” input in the Deconstruct component

Yes. Try it and see.
