Help CubeMX HAL and DMA2D

Help is needed for Alpha channel input (CM_A4 an CM_A8) in combination with the HAL_DMA2D_BlendingStart(...) of the CubeMX HAL.

It seems like FGCOLR is not set neither with the call nor with Dma2dHandle.LayerCfg.

Furthermore the entire blending process is not clear to me. How to select / unselect the foreground layer, background layer and background color. What is needed for a simple CM_A4 + Color -> RGB transformation. A code snippet or similar would be great.

Thanks in advance.
