@Emma-Echter Pedant never, Nerd, and nerd is good š I love nerds and consider myself a little nerd.
Yes I didn't mention the color reference (ColorChecker) because is the only thing that really works great. I love it! ColorChecker are important because camera manufacturers don't make cameras that give you right accurate colors, not even if you shoot in RAW. They compete with each other and they enhance the colors to be more attractive to potential customers. Some brands are known for beautiful skin colors, some for beautiful skies, etc. And then, the RAW issue, the information that the sensor catch in light have to be translated to ones and zeros so there's always a filter that have to be interpreted. Not even different persons view colors the same, so, the ColorChecker creates a Color space based completely in your lighting. You have to make a photograph with it in it with the lighting you are going to use for the shooting and you are good to go.
I don't say it gives you accuracy because I don't think accuracy exist, but gives you consistency. And in practicality it gives you accuracy because the range of change is far from the human brain to notice, I was a little nerd there.
Have an amazing day and keep up the good work!
