No paint brush used only the selection tool, no color added used only the color adjust slide. Was done in two layers. So no pixels added huuuummmm so if you think colorization is difficult well if you can work the color adjust slide and use the selection tool your 99% there enjoy.

Rob, again no matter what you do with your editing, you always get great results. Tigs=^..^=

Rob, I've viewed the original image, and the by you achieved result.
I've read your narrative and additional comment. Think that you try to seduce us to do an attempt, ☺ .
If so, I have to disappoint you. Simply because your masterful way of editing can't (hardly) been improved.
Would be a waste of time with a lot of frustration from my side as result.
So, let me only enjoy the result of your done, and by me admired, effort, my friend!

Very nice colourisation of this old find. I wonder what life she had, that's what I like about pictures such as this.

I have no clue as to how you achieve your fabulous results - just that they are splendid.
Your talent in the colourisation is enhanced by your incredible 'feel' for just the right colours for each work, making them look so natural.

This really is an outstanding image, with lots of clues with which to try to identify it... I say "try" because it did foil my efforts. The details on the door lintel above the girl are varied and the machinery I can see through the opening to the right of the door is in such a position as to make me believe it's a part of what's behind the scene's decorative door, essentially that the concern behind that door extends to the right. The business on the left is obviously a cafe, but the door and business behind her is only a guess. We can see the shoulder of a workman standing in near shadow at the very far right, on the other side of that pallet (?). Add in the machinery and the depth of that opening, plus the two small characters on the door frame, on either side of the girl, who appear to be reading oversized books, leads me to think this may have been a printing company. Above, the caricatures of the bishop killing a snake on the left, and the queen holding a child on the right, may simply be decorations, as are the crowns above them (unless, of course, the name of the company has a hint of royalty to it?). Whatever the case, the biggest clue to me are those two wee fellas holding the huge books. In the past several centuries, characters like those were indicative of people or establishments associated with books; their production, selling, or use. For me, Rob, your colorization of the scene gives it a feeling of mystery, as though I was looking at a somewhat newer view (in the early days of color photography) that somehow managed to capture the impression of either the beloved daughter of the owner or a young lass who died there in an unfortunate workshop accident. I like how some of the images you choose to colorize and submit make me really think... at my age that's a healthy form of exercise.
