@cooloutac - Interesting video, but not the final authority. He has an odd definition of indirect sunlight. Unless he is in the southern hemisphere, his south-facing window provides substantial direct sunlight for most of the day, even a couple of feet from the window.
For sure outdoor direct sun would be too intense for all of the Elasticas that were grown under shade for indoor use where light is much less intense.
The dark burgundy Elasticas are just as prone or more so to too much sunlight as the variegated varieties. In any case, I don't think too much sun is a problem for most owners of indoor plants.
