Red light has the longest wavelength that human eyes can see.

Having a longer wavelength than the other colors, red should appear closest.

Those above the "toe" tend to have much longer wavelengths.

At those longer infrared wavelengths, it is very faint and red.

Our sense organs are not designed for light and sound waves of such long wavelength.

Therefore the effective index is changed, especially for longer wavelengths.

In other cases an absorber for the longer wavelengths is used.

This means that longer wavelengths travel faster through these materials.

Note that, there is no dependence on the energy at longer wavelength.

Nothing about "what it is like" to see blue or red tells us which light has the longer wavelength.
