What's the difference between Sea and Sand and Morning Light?

In subtle tones of blue and beige, Sea and Sand and Morning Light bear the same design, but they are not the same pattern.  Both have a white background, but Sea and Sand is coupe with Suprema flared mugs and 6¼ inch bowls.  Conversely, Morning Light uses a standard rimmed plate style, with Occasions cups & saucers and 7¼ inch bowls.  In addition to the floral band on the rim, Morning Light also has two coloured bands circling the centre of the plate.

Sea and Sand was introduced in the Livingware line in 1990, and it was discontinued June 1995.  Morning Light, in the Occasions line, must be from 1988 or 1989, taking into consideration its late 1980s backstamp and that its cup also is made of Suprema.
