could also draw a white rectangle using PIL
then using it to create a sprite
use that sprite .color to change the color.
something like
import Image
im = Image.new('RGBA', (600, 50), (255, 255, 255, 255))
im.save('from_pil/life.png')
...
class Life(Sprite):
def __init__(self):
super(Life, self ).__init__('from_pil/life.png')
self.colors = [(51, 198, 244), (248, 152, 29), (237, 32, 36)]
self.color = colors[0]
def update_color(self, v):
self.color = self.colors[v]
