Progress bar turns red unexpectedly

[rantingpirate]

Description

For whatever reason, the red->green color progression gets interrupted by red a little over halfway through.
After some experimentation, the range is about 57.3214286% to 58.3333333%.

Code

from time import sleep
from progressbar import ProgressBar

with ProgressBar(0,1000) as bar:
    for n in range(565,590):
        bar.update(n)
        sleep(.5)
