UPDATE2: The pink tint has now been explained by Konttori (Nokia dev) as being intentional. It is called over-saturation which actually makes the colors more visible during bright sunny outdoor situations. It was never really intended for indoor use and hence this maximum brightness is not even accessible manually via the brightness bar. So this isn’t actually an issue. Also, apparently the colors have been adjusted in PR1.1 to make it more consistent at all brightness levels except the maximum. N9 even at its second brightest setting (which is accessible manually via the brightness bar by setting to highest) keeps the color consistent and is still brighter than the maximum brightness of SGS2. So you can say that the over-saturation maximum brightness setting is just an extra bonus for bright outdoor use.
