Here are some attempts at correcting some of the published slides.
In each case, there's the original faded slide, then a version with levels corrected in Photoshop. Finally, there's a version with the levels corrected plus a hue correction. The success of the hue correction on the test pattern and Bisquik box indicates to me that CBS did indeed have a hue shift problem due to lag in the image orthicon, as the color sequence was RBG, and red is shifted toward blue, yellow towards red, green toward yellow (not so obvious) and blue toward green.
