Why are most night modes red tinted but actually blue gives greenish tinted?

Question

Is there a particular reason as why red tint is better, compared to just straight up removing blue?

Personally the green tint for me is better then the red one

Answer 1

I think the point is to reduce the amount of blue wavelength light hitting your eyes. IIRC blue light has adverse effects on restfulness, so reducing it at night is beneficial.
