What would be the control, independent and dependent variable?

im doing an science experiment for science fair due in 2 weeks. my topic that im doing is, does it matter what colors are in a image in order to create a afterimage? How long does an afterimage last? How long does it take to occur? Im testing 10 different people, using the same images, each image is different in which the colors are different. So,... what would be my control, independent and dependent variable?What would be the control, independent and dependent variable?
Your control would have no color and see if there is an after image


Your independant variable is color


and the dependant variable is the afterimage... thats for just changing color.
