Find Different Color Game with Python Turtle

Make a fun game that tests how fast you can identify very small color variation. You can use colorsys library to vary hue, saturation, brightness, or any combination of them. Make the game more difficult by reducing the amount of variation as the level increases. Also, make the size of variation smaller as level increases.

while size > 0:
    draw_square(0,0,size,angle,(random.uniform(0,1),random.uniform(0,1),random.uniform(0,1)))
    size -= 0.1
    angle+=3
