It's always like this, once we know the answer everything is easy.

OKey.... and the the answers is... ?
I mean, how did you cheat?

If I told you:

"Plenty of apps to show the RGB value of any pixel on your screen, directly or indirectly. With Gimp only: File > Create > Screen shot plus pointer dialog, on Linux you probably have xmag already installed."

Would that be enough of an answer for you?

yes, I have Gpick and MATE color picker, but they give hexa, RGB and HSL, but not the "Hexadecimal" as #123, but #123456...
How do you transform #123456 to ➤ #123?
if simple color could work, like #ff00ff ➤ #f0f, how do you do #2a64c2 to #123? Do you do (2+a)/2, then (6+4)/2 and (c+2)/2 ?You raised a great question.

As I wrote before, I found the solution by chance, just by paying attention to a small detail and Eureka!

But I only did this once, which was in the example I posted, and I didn't realize that there could be other cases like the one you mentioned (#2a64c2).

So I tried to figure out how to do the conversion for the case of repeated pair codes (aabbcc, 112233, etc).

I wasn't able to.

But, my failure was that I tried to find a color # on the Guess My RGB website that was not a repeating pair and see what code would be generated.
With this I would try to understand how the conversion was done, trying to achieve the same result.

What happened is that I tried on almost 20 new colors and they were all in the form of repeating pairs.

Therefore, I believe that there will not be colors like #2a64c2 among the colors generated on the website, but always colors in pairs.

In hex it is RRGGBBAA the extra that does not show in Gimp color picker is the Alpha channel.  You get a better display in Inkscape. This made in Gimp with 50 transparency. 80 hex = 128 halfway between 0 and 255 ie 50 % 



so you want #123456 -> #123 , that does not make sense If you want 3 numbers, it is decimal 191, 245, 139
