Okay Everyone,
Thanks again for all of your assistance and patience with me. With the personal hands on, screen sharing assistance of CharlesMx, I was finally able to get this thing working.
Basically what we did was use the theory that BobRay suggested about "System Setting" page color value, as well as the TV value setup. I won't go into too much details, but the system setting option allows me to change the color for entire site (same as I was manually doing it in the CSS file).
And the TV setting allows me to set/change the color for each page individually, overriding the system setting, unless the TV is set to default, then the system setting will override it.
Here is the code that allows me to do what is mentioned above, used in my header chunk containing the css files locations:
<link href="assets/templates/advanced/styles/[[!*cssSelector:isnot=`default/default.css`:then=`[[!*cssSelector]]`:else=`[[++cssSelector]]`]]" rel="stylesheet" type="text/css" />
Again, I really appreciate everyone's input on this as it helped me to understand more clearly what I wanted to do.
Let me know if you have any questions, and I will be glad to share move of what I've learned.
