Do you now know at least that white balance and brightness are different from each other? You have yet to acknowledge seeing a warm or yellow tint in any Rezound pic that I or you have posted or linked.
The pics you took and posted had white balance issues.
This was resolved in another thread...it is only true if you use the default filter in the wrong setting. Switching to "incandescent" for incandescent lighting, for example, completely fixes that. Thats what those modes are for. To compensate for different types of lighting.
This was acknowledged in various reviews as well, which is why reviewers typically ignore it.
