I need Illustrator script to find a combination of numbers in a range

问题

I need to be able to find colors based on the RGB number brake down. I am not 100% how to make this work. Here is kind of what i am looking for.

\var aDoc = app.activeDocument;  

var rgbCol = new RGBColor();  
rgbCol.red = x >= 200  &&  x <= 220;  
rgbCol.green = y >= 200 &&  y <= 220;  
rgbCol.blue = z >= 200 &&  z <= 220;  

aDoc.defaultFillColor = rgbCol;  
app.executeMenuCommand("Find Fill Color menu item"); 

Each one of the RGB numbers can be different from each other. Any ideas?
