when vox started to go liv e with their new layout templates for personalized banners (due to the menu layout changes as have witnessed yourself), i realized that most of my old, photoshop brush banners no longer match the new colour schemes.
i actually really hope that vox allows us to choose the colours. as well as colours for our text (i.e. subject heading and links).
for the time being, for those that like to match your banner designs to the tri-colour schemes, i have created 'swatches' for you to use when in photoshop (just use the eyedropper on these swatches to get the colour you want).
