Description
*AA = Antialiasing, because it's totally fun to type the whole thing out all the time.The human eye does not interpret differences in input of light linearly. Our eyes are more sensitive to changes when there is lots of light. In computers, they deal with this feature in human vision with something called 'gamma-correction' to have photos (and prints) more accurate to how we actually see them.
Of course, the differences between the two white blobs are subtle. Of course, no pixel artist is gonna mathematically calculate every color to have better AA but being aware of this feature in human vision will help an artist avoid having buffer pixels so dark it functions very poorly for smoothing out their pixel art.

Is this correlating in colors, too?
E.g. smoothing #ff0000 on #00ff00: Would #c0c000 be better for a halfway color than #808000 ?
Or should you use HSV/LAB rather than RGB to get a better fitted color?

Unfortunately though, I have no idea if LAB is remotely accessable in my drawing programs
And yes, I believe that this is similarly correlating in colors as well.

Well, my idea was that the LAB-system is actually made to represent the subjective feelings for color.
As you may know, A is standing for a green-red scale while b represents a blue-yellow scale.
As such, finding a smoothing-color is reduced from a 3D-problem to a 2D-Problem.
The L-value represents brightness.
The difference regarding your Tutorial would be:
-> Finding a 3/4 brighter color by hand (if you don't have a fancy brightness-bar) is easier.
-> as scales are logarithmic, found colors are subjective "in between" the original two colors. However, if you look at the rgb-values, the green-part is much smaller while the blue/purple-part is bigger.
So, my guess was that using LAB the found smoothing color would be even better fitting with the surrounding colors, because it would not only adapt the brightness but also the hue to the human subjectiveness. ^^
However, as I'm not a professional/well experienced pixel-artist it's more a question to you than a fact.

Part of me admires your intellect, and part me thinks you've gone completely insane.
...Keep up the good work! ^^

I don't know. The right side looks better to me... Or maybe that's what you meant?
