How do you color-code "nodes" in your KNIME workflows? Tips for visual organization

[rfeigel]

I’m not sure what you’re trying to do. As far as I know, there’s no way to change the color of Knime nodes without getting into their code. Knime does have a color coding system which makes sense.

Why nodes are different colors?

Hi @albireo Yes the colors have meaning, they are used to classify the node types: Red: writer nodes nodes, like Yellow: general data manipulation nodes like: Orange: reader nodes, like: Light blue: Loop control nodes: Light green: Model Learner nodes, like: Dark green: model predictor nodes, like: Brown: Utility nodes, like: Blue: Visualization nodes, like: Gray nodes are components, see here for more info on them: KNIME Components Guide Purple nodes are s…

Changing it would impair workflow portability. Finally, some of your coding requirements appear to be dynamic. What kind of logic would you use to color code these?

Most Knime nodes provide failure warnings, e.g. trying to perform a math operation on a string and warnings, e.g. node produces an empty table. I don’t know how you could produce a color/warning which notes correct/incorrect output. What criteria would you apply for this?
