Color code each row alternately in repeating group

Simply, you will put a group inside the cell to cover the whole cell. Then, you will set this group’s background conditionally. Default, set it to some color. If Current Cell's number module 2 is 0, set it to some other color.

See this group, default red and conditionally gray:
