Infinite loop if image doesn't have at least 4 colors

I tried to load our company logo and it crashed the page. Apparently the script tries to find at least 4 colors.

I ran into this bug as well with the gradify.py script. My cpu started running at 100% and the process just kept running indefinitely. A stack trace shows that the script is getting hung up here:
in get_RGB_diff return abs(1.4*abs(old[0]-new[0])**(1/2.0) + .8*abs(old[1]-new[1])**(1/2.0) + .8*abs(old[2]-new[2])**(1/2.0))**(1/2.0)

Here's the image I am using:

@maaaaark I ran it on gradifycss.com and it produced a gradient correctly

@oliversalzburg I've temporarily coded an early exit for photos with less than 4 colors; after exams I will include code that creates gradients for [1-2] colors.

@fraser-hemp Ok, it looks like my problem was due to me changing the black_sensitivity argument's value in the __init__ method. I set it back to 4.3 and it works fine. Apologies for cluttering up this issue.
