By this version, testing had shown us that the subtask routine being on the far right was confusing users. A common refrain was that they had to look back and forth. In this instance, both tasks and subtasks have been moved to the main left navigation area. As the user completes needed functions, the bright orange CTA button would enable and the user could continue to the next subtask.
Color is used very strategically in both AML and Iris; orange is used judiciously and only for calls to action, warnings, and important status updates.
