Detect colour.
You can use multiple light sensors, block one with a filter that only lets through green light and block the other with a filter than only lets through red light, another for blue. You will be able to tell the colour by the brightness. This will give you a rough idea, it will not give you an extremely accurate colour measurement though.
The TCS3200 color sensor – shown in the figure below – uses a TAOS TCS3200 RGB sensor chip to detect color. It also contains four white LEDs that light up the object in front of it. Specifications.

Researchers from IBM and Pfizer have published...The visual cortex sends this color information to other parts of your brain so you can process what you're seeing and decide how to react to it. This is how your brain decodes millions of color signals and lets you see in color. The entire process happens in as little as 13 milliseconds (1/80th of a second).And, because different colors reflect different amounts of light, you can use them to detect the color of the reflected light if you calibrate the system accurately. Below is how you might configure your color sensor: Vout is the voltage that changes with the change in intensity. So, as the color in front of the sensor changes, Vout changes and ...DOI: 10.1098/rspb.1992.0074 Corpus ID: 35694740; Dichromats detect colour-camouflaged objects that are not detected by trichromats @article{Morgan1992DichromatsDC, title={Dichromats detect colour-camouflaged objects that are not detected by trichromats}, author={Michael J.

However, many colour blind children can learn to identify colours correctly even if they don’t see them in the same way as people with normal colour vision do. For example, children quickly learn that a fire engine is ‘red’ and when they see other items which look the same colour as a fire engine they will identify that as ‘red’ too.
