For scoring tube chains in round up: do the tubes need to be in contact with tubes of the same color or can the colors contrast? an example would be a stack of 6 red tubes presed against one blue tube on a goal post. The bottom red touching the floor will not be counted but will the rest of the red tubes affectivley “chain” touching the blue tube be scored?

The tubes do not have to be the color. The definition of scored in reference to tubes touching other scored tubes does not specify that they have to be the same color.
