Many people have speculated over the last 80 years or so about the possibilities of using colored paper to boost response-rates to surveys and questionnaires, and several studies have been carried out. Most of these enquiries report no significant effects from using colored paper, although there have been some exceptions. In this investigation we pooled together the results from all of the experimental studies known to us on the topic and we carried out a meta-analysis to see if there might be a positive effect for colored paper overall. The results indicated that this was not the case, for we found no significant differences between the response rates to white and to colored paper in general. However, when we considered separately the most common colors used, it appeared that pink paper had the greatest effect.
