These scales are intended to be used when explicitly setting the midpoint of the scale. The Plotlycolors argument accepts explicitly-constructed color sequences as well, as lists of CSS colors: Warning: If your color sequence has fewer colors than the number of unique values in the column you are mapping to color, the given colors will be mapped for some values and random colors will be mapped for other values : The example above assigned colors to data values on a first-come-first-served basis, but you can directly map colors to data values if this is important to your application with colors. The Plotly Express color_discrete_sequence argument accepts explicitly-constructed color sequences as well, as lists of CSS colors: Warning: If your color sequence is has fewer colors than the number of unique values in the column you are mapping to color, the colors will cycle through and repeat, possibly leading to ambiguity: The example above assigned colors to data values on a first-come-first-served basis, but you can directly map colors to data values if this is important to your application with color_discrete_map.
