About complete white image having values (254,254,254)

[pd2871]

The code will not be able to detect complete dominant white images with values like (254,254,254).

Please modify the code of get_palette() to:

r, g, b, a = pixels[i]
            # If pixel is mostly opaque and not white
            if a >= 125:
                if not (r > 255 and g > 255 and b > 255):
                    valid_pixels.append((r, g, b))

Setting the threshold of 250 is causing the problem

Or at least make it configurable:

old:
def get_palette(self, color_count=10, quality=10):

new:
def get_palette(self, color_count=10, quality=10, ignore_white=True):

and only do the thresholding if ignore_white is True.
