I don't like that if someone changes the slider parameters (range or steps) 800 lines higher, the hard-coded constants (20 and 19) here would need to be updated too (easy to miss).
How about avoiding the constants and making the code a bit shorter, with a function like:

    def update_lowslider(self):
        low, high = self.controls.threshold_low, self.controls.threshold_high
        if low.value() >= high.value():
            low.setSliderPosition(high.value() - 1)
        self.update_color_schema()

And similarly for the highslider below.

self.assertFalse(msg.not_enough_instances_k_means.is_shown())

def test_color_low_high(self):
