My experience of sitting in on many, many transfers from film to tape of my footage is that the most useful chart of all is a correctly exposed gray card. If the card is shot correctly, the colorist can neutralize everything correctly. After that s/he rolls into the scene and starts tweaking contrast etc.
“Shot correctly” means placing the card in what you have determined to be “white” light. For instance, if you want the effect of late sunlight streaming in with its orange cast, you would NOT put the card in the sunlight. Instead you’d light it with an HMI or some other “daylight” unit. If by mistake you placed the card in the sunlight, the colorist would pull out all the warmth.
But talk to the colorists you work with, the people who will adjust the color, contrast, etc. of your footage. Ask them.
