Changing Lightness of Matplotlib Color

import matplotlib.colors
import colorsys
import numpy as np
def add_lightness(color_name, L):
    Receives a color name ("red", "tab:blue", "xkcd:green", etc),
    Returns RGB values of same color with lightness L added to it (can be negative too)
    color_hls = colorsys.rgb_to_hls(*matplotlib.colors.to_rgb(color_name))
    new_color_hls = np.array(color_hls)
    new_color_hls[1] = new_color_hls[1] + L
    if new_color_hls[1] > 1.0: new_color_hls[1] = 1.0
    if new_color_hls[1] < 0.0: new_color_hls[1] = 0.0
    new_shade_rgb = colorsys.hls_to_rgb(*new_color_hls)
    return new_shade_rgb

add_lightness("gold", 0.1)
