I'm designing a top-level product landing page for an e-commerce site. The
design consists of a main banner image with marketing messaging spanning the
full width of the page, with 4 content boxes aligned horizontally under the
main banner image with equal spacing in between each so that they cover the
same width as the main banner image (similar to Apple's landing page).
The 4 boxes' header fonts and background colors - different color for each
box - belong to those in the color scheme of the banner image (background
images are lighter, washed out versions).
The banner image and information in 2 of the 4 boxes is set to change on
each page refresh. When the banner image changes, it also changes the
background and header text colors on the boxes.
If a visitor arrives on one of the landing pages, leaves that landing page,
but then returns to that same landing page (via "Back" button or site
navigation), they'll see a page with a different banner image and color
scheme for the 4 boxes. I'm concerned that this can cause the visitor some
confusion. The main marketing message in the banner image won't change, but
the colors of the page and the sub-boxes' content will.
How do you feel about changing the visual elements on a page and potentially
presenting the visitor with new color schemes upon their return to a page?
