Definition :
Subjective colour changes cognitively dependent on how the brain and eyes perceive it. It can be defined as the way a colour looks by the way you see it.
"On the other hand, OBJECTIVE COLOUR means a colour would be independent of the way humans perceive the colour. Objective colours would be immutable, never changing colours independent of human perception.
NOTE:
(The word “Subjective” means existing in the mind and not independent of it.)
(The word “Objective” means existing independently of the mind or perception.)
HERE IS AN EXAMPLE of the difference between subjective objective color:
If color was truly objective your red car would always be the same color red independent of lighting conditions. But the way that the rods and cones work in your eyeball, and the way the visual cortex in the occipital region of your brain processes the way you see the color then your car is different under sodium lights, bright daylight, florescent light, dull evening light just before sunset, or halogen light. In this way the red color of your car is subjective color, not objective color. Objective color red would remain the same red no matter what situations it was seen in.
Probably the hardest concept to fully grasp about color is that color is all in your head. Literally. It's a sensation, just like touch. Like any other sensation it's (usually) caused by physical reality. But it doesn't have any physical reality of it's own--at least not outside your body. And--this is the hard part--color is not a property of the thing that's causing the sensation. In other words, grass is not green and the sky is not blue. Rather, they have physical properties that make you perceive green and blue, but even that's true only in some circumstances.
CONSIDER:
The color you see for any given object depends, in part, on the light you see it under. An extreme example of this is that the color of your car will likely change so much under sodium lamps that you may have trouble finding it in a parking lot at night. But, as you may know, colors change even with less extreme lighting conditions--when moving from a room lit with incandescent bulbs to daylight for example.
If colour were an intrinsic property of an object, and it was only the perceived colour that changed under different lighting conditions, you could match the object's intrinsic colour in printed output, say, under any lighting conditions, and the colours would then match under all conditions. However, because colour is not an intrinsic property of the object but rather a sensation, the only thing you can match is the sensation that a particular colour induces in your visual sensory system. That sensation will change under different lighting conditions, and it will usually change differently for different objects. So the best you can do is match colours under specific lighting conditions."
