Here I am with another one-million dollars question: do you know that terrible problem of scanning traditional artworks?
Like... colors being totally ruined, pics looking horrible when they were actually pretty enjoyable before they were scanned, and such things?
It seems to be a UNIVERSAL problem so just to know I'm asking how you usually deal with this matter...is there any way to make pics look a bit better?
Which scanners work better than others?
From my side, I can say that using Color Curves in Photoshop is a pretty good way to correct the colors.
I started using it just recently and it totally gives better results than the things I used before. But maybe some of you know even better methods
Share your opinions!!
And feel free to share your pain and frustration about this problem, if you ever encountered it D:
Stuck 
Sometimes i gotta use Photoshop tho. idk about any other way. sorry. D:
I usually edit them on Photoshop (with levels or curves too) to try and get something close to the real thing, but I'm not very sucessful.
Watercolor is always a problem for me, the colors don't look smooth or vivid like they do on the paper even after digital editing, it is quite frustrating.
Generally, I'd fight this by simply upping the contrast on the original piece, so it'd scan something like how I wanted. Orange hair having a highlight of yellow, a main color of orange, and a lowlight of a red so dark it's almost black, and out of that I'll get a decent head of orange-red hair on a character.
