grafifypalettes for scale & fill functions
graf_col_palette_default functions generate colours for
grafify scale functions.
graf_col_palette picks sequential colours when the number of discrete colours needed is less than that in the palette. This is the default for
ColoSeq = TRUE. If the number of colours required is more than that in the discrete palette, it fills intervening colours using the
graf_col_palette(palette = "okabe_ito", reverse = FALSE, ...)
This generates required number of sequential colours from the chosen grafify palette when called by scale functions of ggplot2.
graf_col_palette_default picks the most distant colours within the palette, rather than in the sequence they are in the palette, when the number of colours required is less than that in the palette.
Colour order can be reversed in both functions.
When only one colour discreet is required, and you want to
reverse the colour palette,
ColSeq should be set to
