Hey guys im a first timer on PF, and im very new to the whole physics area but im starting to find it very intresting 
Ive got a question about the optics of a normal camera lins of a mobile phone that perhaps someone can give me answares about of even point me in a direction.
Question: Im trying to figure out if the camera lins of a mobile phone can pick up specific colors/unique reflections in liquids that are transperant/invisible to the naked eye.
For example 1: if there is a transperant liquid that could be used to make barcode and scanned with a mobile phone. (Not very practical but all i could think of
)
Example 2: A transperant liquid with a specific color/unique tranperant reflection that is unseen by the naked eye but will still be seen by a normal mobile phone camera.
Just like how a camera phone can pick up IR waves but instead pick up unique tranperant colors or pick up reflections from example a invisible barcode.
Ive tryd using my buddy google about the optic spectrum of a cellphone camera lins but no success :(
Im most likley mixing up the concepts of optics and spectrum or something so try not to be to harsh
