>The results show that the sensor is able to distinguish black from white under both dark and bright light settings. With "Black White Difference" the table shows a significant difference above 20 for all black-white readings. It also shows that the surface did have a small impact on the readings as the "Black White Difference" changed according to the surface. It is also worth to notice that the "Black White Difference" was generally larger under bright light settings.

> As an extension we also tested the sensor in a setting where the to colors to be distinguished were closer to each other. For this purpose we chose green. The table shows that the sensor generally has a hard time differentiating the green colors regardless of the surface. However it seems to be possible under bright light settings with a paper surface and under dark settings with a plastic surface. It is interesting that the "green difference" changes from nothing (0) to 4 when changing the surface under dark settings. The reason for this behavior might be that plastic has a better capability to reflect the light from the color sensor due to it's reflective surface.
