If the sky is blue because of the color of ocean why are sunsets golden?

Here's the full explanation: The sun's light rays enter the Earth;s atmosphere and due to the differences in optical density between the atmosphere and space, the light rays are refracted. Red is refracted less and blue is refracted more, therefore in the morning, when the Earth is on a greater angle to the sun (in terms of where you are viewing from), the red light is refracted so that it fills the sky. The same happens when the sun sets. As with the sky being blue during day time, that is due to the same effect but since during day time the viewing angle is less, blue is viewed. Note: The ocean isn't blue because it is reflecting the blue sky, the ocean is blue because water IS blue. Water has a slight blue hue that is visible in large amounts. That is why oceans (large amounts of water) are blue but bottles filled with water (small amount) are not!

I think it has something to do with light's wave length. From the observers point of view the shortest distance from the light source which is the sun is at noon time and the longest distance is during sunrise or sunset. Which mean blue has a shorter wavelength while red has longest. Of source light has to travel through different medium and the properties of reflection and refraction tends to influence that shade of color to what we normally see.
