in each frame to allow for post-production
This is a compromise with shooting speed of course.
It's a playoff of images-under-constant-light versus images-correctible-for-light

There are some common colors in the mural, in the outline, and in the credit blocks, we can also use as semi-objective references for color/density matching across frames, but yes - the photo assistant will probably spend much of her time running back and forth with a ColorChecker SG.-R

checker, a gray card would do. Since you will probably use a large
overlap anyway you can mount it on an arm such that it is in one corner
of the image. It doesn't need to be sharp, only larger than twice the
blur in order to ensure you have still a valid gray in it's center.
