Julia's border "ingredients" are different than those that are in my portrait border:

For mine, I have: Gold= 834, 3046, and 833; Brown=830, 3031, and 3808; Pink=3064, 21, and 3773.

I needed to do differently because the color harmonies are different in Julia's portrait.

A working image, showing Julia's border color shifted eleven degrees to the right in PS (reducing the 'red' component).
Yellow becomes more greenish and pink becomes orangish.

As I said back on December 22, 2020

Taking a crop of an earlier process photo, and doing the 180 hue shift,
to see what thread combo I would need to achieve the light purple,
(or did I want a less contrasty combo, for a less 'heathered' result?)

Possible threads for Julia's background

I was rather sure of 28, 30 and 3839, wishing a less 'heathered' background, achievable with the lighter purplish blues.
(But I sent for the darker bluish purples so I would be prepared in any case.)

Getting the greenish yellow element in the border was easy, as I already had the threads on hand. Getting the orangey-pink took a few trials, as my first test combos were too reddish.

But obtaining the correct brown required four trials! The dark teal I'd used in my brown created a sour note. I remembered the dark bluish purple 792, which I didn't use for the background. I tried it with the dark brown 3031, and the olive 730, but that was much too dark. So I traded out the 3031 for the 830 greenish brown I'd used in my brown. I finally have a combo that 'sings' in harmony with the rest of the border, and with the background, as well.
