Why does we see sky like blue in maximum time?

We know violet has less wavelength, so we should see sky like violet. My assumption is that, violet is not primary color and not sufficient in the spectrum so we see blue because after violet, blue has the shortest wavelength?

Edit: Because our eyes have sensibility for three primary colors so we may see primary color most but, If a people is blue color blind then what sky color will he see?
