I can read color hex codes just fine. In fact, while writing my CSS, I often have a shade of color in mine and I just go ahead and type out its hex code by guesswork and then fine tune it by changing the R, G, and B values. I am not colorblind. I never thought this is a special skill! It's just basic understanding of hexadecimal, the RGB color model, and additive color mixing.

The nice thing this video helps me with is to give a name to every RGB color code. This is something I had always found difficult even though I knew what each RGB color code would look like. Giving a name to every RGB code makes it easy to communicate colors to others.
