Thank you for your thoughts guys. You've given me a lot to think about. I'll put up clips for the classic settings for Hoth and the closing ceremony using both the older settings and the latest settings so you can tell me what you think.
towne32, you're right that the older classic settings are very similar to the retro settings in terms of colour, the main difference is the saturation level which is a fair bit lower on the retro settings and the contrast is slightly lower as well.
