+ This colour scheme was generated by the gecos software. See<br/>
+ Kunzmann, P., Mayer, B.E. & Hamacher, K. Substitution matrix based color schemes for sequence alignment visualization. <em>BMC Bioinformatics</em> <strong>21</strong>, 209 (2020). https://doi.org/10.1186/s12859-020-3526-6<br/>
+ and https://gecos.biotite-python.org/ .<br/>
+ Gecos sets perceptual differences in the colour scheme according to differences in the substitution matrix.
