This picture was taken from Homegoods, as you can see every section is organize by themes like Country Accents, Traditional & Classic, Global Influences and it can be very easily found with those sings on top.
On each display you can find multiple different things like, table decoration, wall decoration, jars, boxes, all that kind of things but without losing the theme.
Every display has a 'little bruchure' of what you can find on each section, on front, that is the first thing customer see before entering to the section, there you can see they try to make it very harmonious, and on each section they can use a different color history; for example on this Country Accents display, they use different intensities of green, yellow green, yellow, and creamy colors to have some balance and be eye-catching and eye-understanding.
