The red only indicates that the connectors are assigned as male pins. If the pins are assigned as female then there will not be red. The breadboard has female sockets and only male pins and wires will connect to them... female pins will not connect to female sockets in the breadboard view. You can assign them either way or mix them (male and female pins) depending on what you are want to do with them. But you are correct, sense these are breadboard adapter boards, the pins should be assigned as male.
