For NFR test ST-52, more clarification needed on the results of the test. I would recommend to have a quantification of the results. Just a "PASS" is not sufficient, due to the explanation of how the test will be conducted in the VnVPlan. You mentioned that you were looking for the code to create distinct colours for up to 20 users, so the test result could describe the amount of users that it was tested for.
