Here the translation of the parts that are on greek

pws loipon pairnoume auto to xrwma  =  So, how do we get this "result" color?

se multiply layer exeis to local xrwma [ to xrwma pou exei otan to xtupaei aspro fws] =  In multiply layer you have the local color [ the color that the object has when it is visible under white light ]

mporeis na to kaneis kai anapoda, dld sto multiply layer na exeis to xrwma ths fwteinhs phghs, kai apo katw na bapseis to local xrwma, kai na kaneis pick to apotelesma  = 
You can do it backwards to, for example in the multiply layer you can have the color of the lightsource and below that multiply layer to be painting the local color of the object that is lighted by that colored lightsource, and then pick the resulting color.
