Based on the table of lighting variations testing on module
for mobile applications, it can be seen that in all lighting
conditions, the module with RGB color model shows that the
success rate of color samples detection are low, i.e. 0%,
0.67%, and 11.33% respectively for each lighting condition
respectively. With the RGB color model, the color of objects
should match the reference value of red, green, and blue
components so that it can be detected. However, it seems that
a dark green, dark gray and dark red can still be detected in
bright lighting. This suggests that in bright lighting, the color
read by the camera is not much shifted from the color of
references used in the module.
