77 * false. For example, some colour schemes are specific to either peptide or
78 * nucleotide, or only apply if certain kinds of annotation are present.

95 * Answers true if the colour scheme depends only on the sequence symbol, and
96 * not on other information such as alignment consensus or annotation. (Note
97 * that simple colour schemes may have a fading by percentage identity or
98 * conservation overlaid.) Simple colour schemes can be propagated to
