Big noob question but what are the red and blue curves representing on the ROC?

Final Y is the target attribute, is it the true positive and negatives ?

the two lines are two ROC curves. The color are based on the configuration of the node. If you can post a screenshot of your visualisation here, this would be very helpful

Here you can find more about ROC curves. https://en.wikipedia.org/wiki/Receiver_operating_characteristic
And here you can find workflow containing the ROC curve node on our examples server: https://hub.knime.com/knime/nodes/ROC_Curve*e3rnMYIl5BZphzl1

Best wishes! Iris
