Resumen de Los problemas de un daltónico

Sergio Falcón Santana , Luis González

• Starting from the application of Set Theory, we try to help a daltonic boy facing a problem: if a mechanism has two red lights and one green light, and this last one is on if and only if one red is on, can the daltonic boy decide whether the mechanism works correctly or not? And what happens if the mechanism has another yellow light between them?
