Change hot tracking colour

I use an Aero theme on my streaming computer. I don't want to change this but the hot tracking colour that shows the selected item on a menu is a faint transparent blue that is almost impossible to see. This cannot be changed in Windows. I have been researching this and I think it is in msstyles somewhere. I would like to change the colour with Resource Hacker to make it brighter or improve the visibility in some other way but it is difficult to figure out what needs to be changed in msstyles. Can anyone help me out with this?

Thanks a lot for the reply. I will experiment with this and see how far I get. I'm not trying to do anything fancy. I just want to make the tracking colour more visible.

Ok I am completely confused now. I cannot find any trace of the image referred to in msstyles. I am also not sure we are talking about the same thing. From my research I thought it was the hot tracking color, but I may have that wrong. I am referring to the slight colour shading change that indicates the selected item when scrolling down a menu list. This is what I would like to modify.

Yes that is what I want changed. Just that light blue highlight bar. On my Windows 7 streaming computer it is much fainter in Aero, especially with AHK menus. I know I can improve this by switching to a non-Aero theme, but that affects other things, especially the way the magnifier works. I would like to change the colour or make it brighter. I really don't know why Microsoft keeps doing this sort of thing. It is like they want to annoy people.

I really appreciate your help with this. I am not a computer novice but this is an area that is new to me.

The display of your first screen shot didn't appear correctly on my monitor for some reason, which is what confused me. I couldn't see what you meant. Now it makes sense.

If you don't mind doing this for me I would certainly prefer that. You obviously know what you are doing and I'm sure it would save me a lot of fumbling frustration. I don't care about aesthetics. The computer is purely a workhorse and I just want a practical solution so feel free to make it as garish as you like as long as I can read the text underneath.

Thank you again for doing all this and for being so patient with my ignorance. I really appreciate this.
