This is a simple scaling of the red, green, and blue channels, and is why color balance tools in Photoshop have a white eyedropper tool.

A pixel with a green filter provides an exact measurement of the green component. The red and blue components for this pixel are obtained from the neighbors. For a green pixel, two red neighbors can be interpolated to yield the red value, also two blue pixels can be interpolated to yield the blue value.

These tool buckets are first kept near the mix table and then as the plaster starts to set are moved closer to the wall that is being worked on.
