Subject: HOw does color affect heat absorbtion?

For my science fair project I want to take celophane and cover glass 
beakers with different colors: red green blue etc.  and shine a sun lamp on 
each different beaker with water in them and see which water has the 
highest temperature after a certain amount of time.  I am also going to use 
different liquids like alcohol and salt water and see if this had an affect 
on the heat absorption.  I am going to use a clear glass as my constant.  I 
looked through your archives and found information on the color of objects 
and heat absorbtion but thought that it would be different if it wasn't the 
actual object but something covering it and also if it was a liquid and not 
a solid.  I just want some information, or a place to locate information to 
base my hypothesis on, and also to understand how the colors might affect 
this  and how energy relates to light and color.
