Hi there !

I'm Willy Kedziora from France and I need some help to something quite... impossible to do for me.

I'm in love with ancient painting and I know that they never used pure black, while they conserve others colors.

For exemple, I would like to replace only black parts ( not the middle black or shadows ) but I can't find the solution. There are always purple in my shadows..

Anybody to solve this ?

Thank you by advance.

Best regards

Another option besides a Masks selection could be: globally adjusting with RGB point-curves within the Tone Curve panel. Or, using the global Grading panel maybe - with the darks selectivity pushed right down.

I am not so sure Grading, nor any other hue manipulation, can have visible effect on a really deep black. But Tone Curve can include a lifting-up of even zero luminance, to a lighter tonality which is capable of showing an effect from changing hue.

Of course true Black cannot show any colour; its red, green and blue components being all zero. And something very close to black is scarcely able to.

In Lightroom Classic you can intersect two masks, on for Luminance (dark color) and on for Color (use the pipette).
