Welcome to the personal webpage of Jeroen Granzier!

My work involves color perception in the widest sense. We are surrounded by color and color gives life....color!

Although color is such an integral part of our life, there are so many things we still need to learn about how we perceive color. My research is about trying to close the gab between the physical word around us and how our brain forms a conscious percept of this. I am particularly interested in how humans perceive colors and which factors influence how colors are perceived. For this purpose I use psychophysics.

I am interested in differences in color perception between individuals and how color perception changes or remains the same under changes in illumination and backgrounds. My interest lie both in low-level features (i.e. eye movements; Does where a person has moved his/her eyes influence how a color is perceived?) and high-level factors (are we ‘better’ able to perceive the colors of familiar objects compared to the colors of objects we do not know?). 

My current work investigates how well we can perceive both natural illumination (daylight) and artificial illumination (i.e. tungsten).

Below you can find a general overview of the articles on color perception that I published.

Feel free to sent me any comments/questions!

Best wishes,
