How or best way to create blended LED light strips to use with DMX lighting.

Please see the attached image for refrence.

I’m looking to create a blended LED light strip like the one in the image.
This lighting will be DMX, is there a way to blend together the differnt lighting/material sections so when the colours move its not choppy/ jumpy?

Please attach video or let me know if anyone has done this before. Thank you
