Now that my semi-autumnbreak is over I started working on a typical slow cooker. Lots and lots of spots to be dabbed so progress will be pixel by pixel with regular time-outs to avoid RSI

And there is the dilemma of colouring and how to tackle it.
First the original, I immediatly fell for this gorgeous photo :

After colourcorrecting according the superbe tutorial I got this :

Lots of yellows and blues appeared and I battled the yellows first by using select - color range - yellows and applied one adjustment layer Hue/Sat - saturation -100 (trick learned from Katrin Eisman's book) which gave me :

While thinking of the next step I started to do some of the "boring" work ... a few hundred dots a day ...
The next step would be the blues and that's where I tried several techniques without finding the perfect solution.
- first I tried the same approach as I did to tackle the yellows but it did not work, not even after several duplications of the Hue/Satlayer (as suggested in the book)
my next try was to select the blues and use the adj.layer selective colours, alas not the desired results
and I tried to find the opposite colour of the blues but there are many shades of blue in this photo so none of it worked
My last try was to add a channels adjustment layer, set red & green to 0 and blue to 100 (also from my KE restauration bible) and I thought it looked best when set to Hue

But this would take out all the colours and also left the damage underneathe the blues on the white shirt visible and I thought the brown colouring needed to be brought back in at the end so for some testing I added a brown color fill picked from the colourcorrected browns and set it to color

When looking more closely at the skincolours and the shirtcolour in the colourcorrected layer I saw more flesh and white colours than the brown coloured testlayer which makes me think I need to handcolour it in the end when I choose the channelsmethod to knock out all the shades of blue.
And this is where you guys come in. What road would you recommend and what alternative did I miss in my survey?
Am I right in assuming this would be a studioshot in which lots of browns in the costume, props and the background were used to create a pseudo antique style because the skincolours look more pinkish than one would expect on a real sepia? Or did staring at it to long make me see things that are not actually there?
