Thank you so much for the detailed response. It has always bothered me wondering which one was correct. While I prefer to watch Harmy' s version for its clarity and overall correctness, it's still a blast to watch the originals I grew up with. My next question would be then if this means the original theatrical release featured the same color errors.

This is probably the most controversial scene in the Despecialized version. There was ample discussion about this scene around page 236 of this thread if you want to look over it.

Long story short, each person remembers that scene differently. The brightness would have been different theater to theater depending on the projector and how good the projectionist was and each early VHS version had different brightness levels. Not to mention the different settings of TVs etc. This means most of us have a different perspective of which version is "correct".

Harmy did change the brightness between v2.0 and v2.5
