Dermablend Smooth Liquid Foundation

I just spent $70 on makeup, but why is the foundation emphasizing any dryness or pigment issue. It isnt covering and looks very cakey and horrible!

I tried the linen shade first based on the pictures from the dermanblend site. It was far too yellow. Is this more rosy/pink in the cream shade?

Is anyone using the colors of sepia or chestnut? If so, are there yellow undertones in these shades? Thank you.

Does anyone know what can be used in place of the Vichy dermafinish color nude #25? It seems to have been discontinued.
