The white color in the dark painting can be very effective. Often it is even vital to create contrast.
Remove the white color patch in the upper center and this blue will almost be invisible. The white gives it light and the ability to shine.
With the help of the white we can also appreciate orange, red and light blue much better. It sort of directs all our attention and focus to the area in the center where pointed orange is repeated in the top area of this painting.
Interestingly, this white patch in the center corresponds to the white figure in the bottom. Even white point to the right of this figure is much more vivid because of this larger center area.
