color sensor TCS3414 help

Hello,everyone.This is my first topic in wanna use the color sensor TCS3414(seeed) to get real RGB values of the detected thing,but by using the example code i can only get the x,y values of CIE 1931 chromticity diagram.I am paying attention to transforming the x,y valuses to the RGB values,is there anyone once use this color sensor or is there anyother good color sensor that can get the real RGB values of the detected thing?


I have used the TCS230/TCS3200 (seems the same) and have a library with documentation in the librarie slink below. These are really cheap on eBay.
