Why do objects have different colors?
Colour of objects Objects appear different colours because they absorb some colours (wavelengths) and reflected or transmit other colours. The colours we see are the wavelengths that are reflected or transmitted. Black objects absorb all colours so no light is reflected.
Is color a physical item?

What colors do LED lights make?
How To Make Colors with LED Lights

- Orange: Red at full brightness, green just a little under half way, and no blue.

How does color detection work in OpenCV and Python?
Detecting the color correction card Determining the color block region Performing histogram matching to transfer the color space from one image to another In that manner you can help ensure a consistent color across all images, even though they may have been captured under different lighting conditions.
How does the color of an object affect your brain?
3) Color is a sensation. When light illuminates an object, the diffuse reflected light enters your eyes, it interacts with the color receptors in your retina, and these in turn send a message to your brain. When viewing familiar objects such as landscapes or faces, the response of the brain is sometimes surprising.
How do you detect colors in an image?
To detect colors in images, the first thing you need to do is define the upperand lowerlimits for your pixel values. Once you have defined your upper and lower limits, you then make a call to the cv2.inRange method which returns a mask, specifying which pixels fall into your specified upper and lower range.
