We've been proud of consistently doing our best to be colorblind friendly with our games. Sagrada is at its core and game about color. We've done our best to find colors that are distinct and preserve the aesthetic of the theme while remaining functional.
We've had quite a few testers and colorblind fans at conventions who have been able to play a full game. Each time, it's been helpful to have a non-colorblind player help organize the dice after they're rolled, and help clarify as needed.
Overall, it really seemed to be a minor disruption to the gameplay experience, and the feedback remained consistently positive from our colorblind players.
