Let’s take a look at the Owen/C-3PO color grading of three official releases and the regrade.

Bluray regraded:

The bluray has the most issues, especially considering the time it was made, ranging from a host of color artifacts (green C-3PO, blue on the sandcrawler, ultra-blue R2-D2, where his dome has a green hue, very dark skinned Owen, unnatural brightness and contrast). The JSC is too red, with R2-D2 almost purple, C-3PO too orange, the sand too red, and Owen red faced. The GOUT looks reasonable for this shot, but I feel the regrade, which is based on the Technicolor print scan, and a number of other references, is the most natural looking by far.
