added correlated color temperature (CCT)
This app is designed to recognize the chromatic coordinate xy in CIE 1931 color space.
You can see the correct value in the CIE 1931 color space chromaticity diagram.
There are various kinds and conditions of light to set white balance

Good It'll be better if it can give more decimal point in x,y coordinate (3 decimal at least?)
CIE1976 Funny app :) However, using CIE1976 (isometric colorspace) would be a better option than CIE 1931. (And that would be great to have a way to pseudo-calibrate the camera more accuratly than just choosing a white balance).
Add XY -> CCT formula I’ve been using McCamy’s cubic polynomial approximation referenced in Color Temperature (Wikipedia) to convert x & y to CCT. n=(x-0.325)/(y-0.154) CCT=-449n^3 + 3525n^2 - 6823.3n + 5520.33 Could you add this to your app? Also duv would be nice, though and additional conversion...
