      It is slightly blue, it’s just only noticeable when it gets deep enough. So yeah we’ve all been drinking blue water lol

      Water IS blue but not enough to explain why the ocean is as blue as it is

      While relatively small quantities of water appear to be colorless, pure water has a slight blue color that becomes deeper as the thickness of the observed sample increases

      Wikipedia

      The color of the ocean is due to atmospheric scattering affecting blue light (short wavelength) more than longer wavelength.
