What to alter in UIcolors.txt to get pale blue active layer indicator back

Hi,

CS6 had very obvious pale blue when a layer was active.

Now I have just upgraded to latest photoshop 26.2 its a horrid grey when inactive is also grey.

Visually its a shock as everything is dead flat and not even a highlight shadow on any of the buttons, panel lines, tools, just black outlines. Like it was designed by a child. CS6 far more pleasing to the eye. Even the icons are sharper focused.

I have solved the terrible rulers, grey on grey couldnt see the numbers, and the divisions are now 0.2mm and before 1mm tall. what idiot has messed with all this.

That ruler fix was using UIcolors.txt to get the backgrounds lighter matching CS6, now I can see the rulers better though divs need making taller .2mm to 1mm. I guess thats deep in the coding and beyond me.

I cannot see where in that UI it controls the colour of active layers.

or is it another editable file in adobe somewhere ?

I also would like to have the active image tab a pale blue, forever struggling to see the active image tab, very bad. end up closing the wrong tab. all we have to go by is 'is the text on it a slightly bolder font' that is hopeless.

C:\Program Files\Adobe\Adobe Photoshop 2025\Required

Cheers
