About ImageJ text can render incorrectly

Originally ImageJ About images were specified to be RGB images. Recently this specification was relaxed. There are text files associated with about images that specify how to render the attribution text. One field is the rendering color. For backdrop images that are not RGB this color is no longer respected. We need to determine whether to ditch the color text support or not and update IJ2 as needed. Alternatively we could create the attribution as a color text overlay instead of stamping it into the Dataset. However text overlay code is not really in place yet.

Migrated-From: http://trac.imagej.net/ticket/1954

Start by tracing how the About image text files specify rendering color and how IJ2 handles attribution on non-RGB backdrop images. Determine whether color text support should be retained or removed, and define the expected behavior before updating IJ2; the text-overlay alternative is noted as not yet implemented.
