It seems that the photo is a bit dark (I see mostly medium to dark tones). At what time of the day was this photo taken?
What do you mean exactly by desaturated/based on luminosity? You used HSL instead of HSV?
The picture was taken with almost no sunlight but it was not completely dark yet. The neons and lights on the street were already on.
By 'desaturated/based on luminosity' I mean I used 'colors/desaturate' and then chose the item 'Luminosity' in the dialog; as easy as that :-)
Take a look and compare them; any suggestion is welcome :-)
Anyway, one can see in the B&W picture that the catchy red has disappeared:
- the red columns at the side of the tower have about the same tone as the blue/green windows of the tower
- the blue and the purple of the Oz-mall bill board at the middle left look exactly the same now
- the red letters ABC on the lower left are barely visible
- even the nice colour contrast between the blue sky and the red neon lights on top of the building has largely gone
So, I did some quick checks. Desaturation based on "lightness" and even the simple "average" preserve more of the red. But not as much as I would like.
When using the channel mixer I achieved something more to my taste when using :
red 90
green 50
blue -10 (indeed I subtract a bit of blue to get the sky darker; shadows become also darker and loose unfortunately detail)
I checked "Monochrome" and "Preserve luminosity" of course.
One has to tweak and fiddle of course to get things right.
Well, just my opinion, nothing more, and I hope it helps.
I think that you are right, I simply desaturated the picutre as a exercise, but didn't give a second thought to it.
But now I can see that the catchy red color is giving a lot of charm to the original picture, and I should try to somehow preserve it.
My idea is, when I'll have some time to spare, revisit the desaturation process for this picture following your -great- advice.
Thank you very much once again.

Thank you!
