Perception is done by your brain. What your eyes do is sensing.
The sensing of light (which may in fact be what you're after) is done much as explained by other answerers. However, the eyes do not know what the signals mean (a camera can "see", but it does not perceive). Those signals from the eye go along the optic nerve to the brain, where they are interpreted into images. This is the really tricky stuff.
Perception does start in the eye -- it involves, for example, particular cells in the retina which detect certain features of an image, such as vertical lines, horizontal lines, movement etc. However, it's still the brain which works out how this all fits together into an image, and what it all means -- for example, what the image is of.
What we cannot know is how anyone else perceives a colour. What I see as red may be what you see as green, or purple, or something else I cannot imagine. It's a mystery...
Even some quite "unintelligent" animals can understand images amazingly well. A pigeon can recognise an image of a tree -- including photographs, drawings, different kinds of trees, pictures from the side or above -- all very much as we recognise whole classes of objects.

The wavelengths that the object absorbs determine to color. Say you see a red object, its red because it has abosrbed all the other wavelengths.

The gadgets are purely the colour i want to confirm. My eyes instruct me the colours it needs to inform my innovations. different species see colour in yet in a various way by way of their eyes. So i could say my eyes supply the object their colour.

light ray has diff. wavelenth.and our eyes absorb those wavelenth the object image form on retina and retina consists of cones which absorb the light and send the colour information to brain.

Light is comprised of various wavelengths of radiated energy. The receptors in your eyes (called rods and cones) react to different wavelengths.

we see tht colour which reflects from the object as white light has 7 colours in it and diffrnt colours appear by diffrnt combination of these colours.
