Basic Pygame Graphics
<p>I am just starting to learn pygame graphics. I drew a circle in pygame and was wondering how I program it to change colors.<br>
For example: it changes colors from blue to red.  </p>

<p>I need it to keep changing colors until I close pygame and it would be nice if the colors gradually changed from one to another instead of an instant change? Any ideas how I could do this?</p>

<pre><code>import pygame
pygame.init()

RED =   (255,  0,  0)
BLUE =  (  0,  0,255)
BLACK = (  0,  0,  0)
SIZE = (1000,1000)
screen = pygame.display.set_mode(SIZE)

pygame.draw.circle(screen,RED,(500,500),200)

pygame.display.flip()
pygame.time.wait(3000)
pygame.quit()
</code></pre>
