When nodes are colored based on a set of different strings in a column, there should be an option how to treat empty strings (missing values). I usually set them to gray, depending on the color scheme.

Expected Behavior

In 0.9.1, the empty string would appear as an option for manual color selection.

Current Behavior

In 0.9.2 nodes are colored simply black. No option to change this anyhow (other than setting a pseudo-value in the table cells).

Possible Solution

The solution in 0.9.1 worked but even better would be a general option to set the color for empty tables because you have to reset this value for every attribute manually.

Steps to Reproduce

1. Load a node table with a colum with values "a", "b" and ""
2. Color nodes by rank with any palette

Context

I have to go back to 0.9.1 for coloring my graphs.
