Hi everyone,
I want to conduct a study on the effect of clothing color on perception using photographs of people. For this, I have chosen 12 different people in 4 different color conditions. I have two dependent variables (voting intention and competence perception). I want each participant to rate the four colour conditions for both DVs but do not know how to exclude the pictures I used for the first DV in the second one to make sure participants do not see a person twice. In addition, I also want to exclude pictures seen for one colour conditions in the other ones (i.e. if people see X in red for the first DV they should see Y in blue for the same DV and not X in blue = within-participant design).

Thank you so much for your help,
Celine
