In strong light or low sun in horizon, blue from sky can have a slight magenta cast. I think the blue layer is getting overwhelmed and bleeding into the adjacent layers.
In the recent Quattro info from Sigma, they have mentioned that the blue layer acts as a luminous layer for the green and red layer as well, it us not clear if that is also the way the Merrill works as well.. But it could explain some of this issues that are sometimes seen when the sensor gets too much light.
Some of the other issues seem to be related to auto wb to me. I tend to adjust awb in post using spp or aperture, since I shoot b&w most of the time w/ dp.
There has been a debate going in the past, on whether...the true base iso for the foveon is 100 or 200. I have always felt 200 worked better in general.
Just bring up spp and check out what the default setting produce. Play around w/ the raw file.. There is a world of difference.. Things that looked bad in the jpg look much better running the raw thru spp. I think this is because the camera does not have the CPU horsepower to do everything correctly to create the jpg vs what can be done in post.
