This paper describes an experiment based on a modified version of the classic Ishihara Test for the evaluation of the degree and type of colorblindness. This work originates from the following observations: commonly used tests for color blindness assessment use color patterns without generating edges between the colors to discriminate. Furthermore, in normal sighted people, edges have a very important role in the generation of the chromatic sensation. For this purpose we created an alternative set of Ishihara plates in which we expand colored blobs until they touch each other, generating an edge. We have developed a mobile application for the execution of the test and a database for storing the data. Preliminary results are here presented.
