Ok. Good to know. But how does this colour chart work? I want to learn, that’s all.
The other thing here is that the print is faded. So it’s not colour accurate anyway. What other sources will you guys be using to find the proper projected print colour and brightness?

I have seen a Telecine (not telesync) of a 35mm release print of Interstellar which is completely different colour-wise to the Blu Ray or DVD. The telecine has a warm yellow-green look with more sunburnt skintones which is very similar to how most photochemically timed prints appear when projected with warm bulbs, while the DVD and Bluray has a cooler blue-ish tone. The telecine looks absolutely gorgeous colour wise, and now when I look back at the BD or DVD, I find them uninteresting to look at.
The gold-toned image is what we’ve come to associate with photochemical prints and 35mm screenings. And as I said earlier, even the Blues in the prints look somewhat violet/purple shifted.
