Before fonts in matplotlib make you crazy again, remember:

1. After installing a font in the system, you need to remove the cache:

~/.cache/matplotlib/fontList.cache

2. If you using Ubuntu, you might need to install Vera

sudo apt-get install ttf-bitstream-vera

Sometimes I want a color just brighter or darker:

def shade_color(hex_color, offset):
    new_color = hex_color
    if len(hex_color) in [6, 7]:
        if hex_color[0] == "#":
            hex_color = hex_color[1:]
        rgb_hex = np.array([float(int(hex_color[x:x+2], 16)) for x in [0, 2, 4]])
 rgb_hex /= 255.0
