Change color of background in trials?

[Sebastian]

Yep! I'm currently working on adding a "color scheme" setting to the trial templates, allowing the colors of the interface to change from trial to trial. At the moment, the plan is for two color schemes to be available (light and dark), and I hope alternating between these two will fulfill this purpose for your experiment. We may add more flexible color options in the future.
I plan for this feature to be available by late October. Thanks for your patience!
