Austin Seraphin has been blind from birth. His iPhone review is enough to make you weep:

The other night, a very amazing thing happened. I downloaded an app called Color Identifier. It uses the iPhone's camera, and speaks names of colors. It must use a table, because each color has an identifier made up of 6 hexadecimal digits. This puts the total at 16777216 colors, and I believe it. Some of them have very surreal names, such as Atomic Orange, Cosmic, Hippie Green, Opium, and Black-White. These names in combination with what feels like a rise in serotonin levels makes for a very psychedelic experience.

I have never experienced this before in my life. I can see some light and color, but just in blurs, and objects don't really have a color, just light sources...

First, I saw one of my beautiful salt lamps in its various shades of orange, another with its pink and rose colors, and the third kind in glowing pink and red. I was stunned.

The next day, I went outside. I looked at the sky.
