Chroma Meter for Android
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).
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...

It'll be better if it can give more decimal point in x,y coordinate (3 decimal at least?)
