Okay, my progress was the following, I wrote a few lines in the file colormaps.py where I create a function called listColormaps() the important thing is that according to the type of colormap it will list the available patterns.

Now, I find it useful to declare in a global way the variables of the colormap types that exist, that is to say: Perceptually, Sequential, Sequential2, Cyclic, Qualitative, Miscellaneous. In such a way that if more patterns are developed it will be easier to extend the functionalities.

# New function to list the actually colormaps on matplotlib
def listColormaps(category):
    # Define a dictionary that maps each category to its corresponding list of colormaps
    colormaps_by_category = {
        'Perceptually': ['viridis', 'plasma', 'inferno', 'magma', 'cividis'],
        'Sequential': ['Greys', 'Purples', 'Blues', 'Greens', 'Oranges', 'Reds',
                       'YlOrBr', 'YlOrRd', 'OrRd', 'PuRd', 'RdPu', 'BuPu',
                       'GnBu', 'PuBu', 'YlGnBu', 'PuBuGn', 'BuGn', 'YlGn'],
        'Sequential2': ['binary', 'gist_yarg', 'gist_gray', 'gray', 'bone',
                        'pink', 'spring', 'summer', 'autumn', 'winter', 'cool',
                        'Wistia', 'hot', 'afmhot', 'gist_heat', 'copper'],
        'Diverging': ['PiYG', 'PRGn', 'BrBG', 'PuOr', 'RdGy', 'RdBu', 'RdYlBu',
                      'RdYlGn', 'Spectral', 'coolwarm', 'bwr', 'seismic'],
        'Cyclic': ['twilight', 'twilight_shifted', 'hsv'],
        'Qualitative': ['Pastel1', 'Pastel2', 'Paired', 'Accent', 'Dark2',
                        'Set1', 'Set2', 'Set3', 'tab10', 'tab20', 'tab20b',
                        'tab20c'],
        'Miscellaneous': ['flag', 'prism', 'ocean', 'gist_earth', 'terrain',
                          'gist_stern', 'gnuplot', 'gnuplot2', 'CMRmap',
                          'cubehelix', 'brg', 'gist_rainbow', 'rainbow', 'jet',
                          'turbo', 'nipy_spectral', 'gist_ncar']
    }

    # Return the list of colormaps for the given category, or an empty list if the category is not found
    return colormaps_by_category.get(category, [])
