Compare your results to the numbers in the color picker at:

Why we use 2 hexadecimal digits per channel and assume 3 are unnecessary?
Two hex digits per color (like E1 for red) give us 256 possible shades for each color — from 0 to 255. That’s enough for about 16.7 million total colors (256 × 256 × 256), which is already more than the human eye can easily distinguish on a normal screen.

If we used three hex digits per color, we’d get over 4,000 shades per color — way more than we need. That would make color codes longer (#E1122FF22 instead of #E122F2), harder to remember, and wouldn’t look visibly better on most screens or in most photos.

So two hex digits are the sweet spot:
✔️ Short and easy to read
✔️ Matches what screens actually use
✔️ Plenty of colors for everyday life
