I haven't see anyone mention using this MOD. But I like how much easier it makes seeing the color you're selecting. Unfortunately, it doesn't have any install instructions.
I replaced my admin_config_colors.asp with the admin_config_colors_withBgImages.asp file, and that works fine.
But how do I use the pop.colors.asp file? It's supposed to act as a popup color picker that fills in the text box with the color selection.
I'm not using that mod, but if what you are wanting is the numerical values, I can send you a little app that will give you the RGB values, the HSL values or the HTML #number for any color you want.
I just ran into the same problem you did TastyNutz. I did some digging and found the problem. Aside from renaming the admin_config_colors_withBgImages.asp to admin_config_colors.asp, you also need to added the folowing line into inc_iconfiles.asp(around line 148):
Const strIconColor = "icon_color.gif|15|15"
There is a linke in the admin_config_colors.asp file, its just not showing up because that Const isn't defined.
