Circles, squares, and dashes in red, lime, gold, blue, and black cheerfully appear in grids on a background of oatmeal (not beige, not grey, but in between and neutral).  The little highlights in the colors make them even more lively.  This midweight cotton from Japan would make great shirts that can double as light jackets, shells, tunics, dresses, tops, shells, and vests.
