In word document, how to change the color of citation from endnote?



I am working in Word 2003  and  EndNote X(2114).  In order to find the citations easily that are formatted as (1),(2),(3)…etc in word document, I want to change the color of citations in word, not to change them manually, but to change them automatically in creating the citations. I just change the front color of in-text-citation, not the background color. Could you tell me how to do this?    

 For example:    

The ETL implementation such as the application described in Byrne [1]. 

 In this sentence, the color of citation [1] is Blue, not the default color.
