How do I invert a recolour layer/mask

[Affinity-Inspiration]

I’m trying to colorize an old photo.

Basically the steps are like this.

load image

Recolour

change hue to blue by dragging in the circle, same for saturation

brush in skin/hair in black, to remove hue

all that goes according to plan.

to color hair alone,

set another recolour adjustment. But I don’t see that layer appear when I again select recolour.

i select layer mask, open channel studio, invert. But it seems to be inverting the original recolour mask, not a new one... because there isn’t one.

what am I doing wrong?

so question.

shouldnt there be two recolour masks? 

Should there be two layers?

Thanks.

After adjusting the colour and painting on the mask, select the main image in layer studio before applying another Recolour.

You can also get good results using gradient maps. Just select suitable shadow, mid tone and highlight colours for hair, skin, clothing etc, invert gradient layer and use black and white brushes on gradient mask to hide or show the colours. This method takes into account highlights a shadows. Change the blend mode on layer option to colour or any blend that gives the desired result, and adjust opacity for realistic tones.
