The coloring scheme is much better than alphanumeric labeling of the smartsleeves & lines, but isn’t very colorblind friendly. I’ve made a suggestion for improvements for red/green labeling (problematic for vials 2, 3 and 15) with minimal changes from the current layout.

In this scheme, the first row of vials has a single heat-shrink tubing tag, the second row has two, etc. This allows you to more easily identify which vial the line should go to, and allows you to distinguish single red vs double green etc.
