Good morning @VAGR_ISK,
the color management in Knime certainly is improvable in many ways. I frequently face the challenge to consistently and dynamically manage colors in large workflows too. Just recently I had an idea and did a quick test.
With your post I took the change to create aa sample workflow that displays how manage colors in a more consistent manner throughout the workflow and in a dynamic fashion to
The following example workflow allows to:
- Reintroduce colors if they got lost
- Allows to save color data temporarily and load it dynamically elsewhere in the workflow
- Reduced workflow complexity by not having to pass the color table down the workflow to merge it back with the data
Since I struggle a bit to imagine your workflow, do you mind to share it so we can combine yours and mine for a solid solution?
Also worth to note that I potentially discovered two bugs. I will create corresponding bug reports and link them here so you can vote for them to get fixed.
Edit: Here are the two bugs you might want to upvote too:
Best
