Mallo-Ware dishes came in at least 10 colors.  The care instructions for dishes reveals that Mallory's beautiful colors will endure forever. This has proven to be the case, although some of the lighter colors are easily scratched and the scratches can become discolored. The careful use of bleach diluted by water can remove some discoloration, but deep scratches can permanently mar the dishes. Although very durable, Mallo-Ware is not microwave safe (it was manufactured long before microwaves were invented) and will melt if exposed tom high heat.

I havebeen able to obtain eight (possibly nine) of the ten colors, with examples presented below. There may be additional colors that I am unaware of- I have seen a White Mallo-Ware advertised on Ebay, but don't own an example yet. Based on my observations of Mallo-Ware coming up for auction on Ebay, I believe that Blossom Pink and Ice Green were the most popular colors.

Buttercup yellow    Ice Green    Hawaiian Coral      Pastel Blue    Blossom Pink
