I have a crash test engineer question?

When they crash test cars and use test dummies. How come some test dummies are darker colored and others are lighter colored. Is the dummies supposed to represent race like darker dummies imitate black people and lighter dummies imitate white people. How come some of them have clothes on while other dummies some are naked with diodes, gadgets wires and sensors exposed?

the dummy color is immaterial what is used is the strips and other indicvators because all damage is filimed on high speed film

The colors and clothes do not matter and are there only because of how they want it to look in the photograph or video.
