Abstract
A card includes a plurality of tiles: (i) a first set, each having a HEX value representing a shade of grey-scale, (ii) a second set, each having a HEX value representing a same shade of grey, (iii) a plurality of skin-toned tiles each having a HEX value representing a tone of human skin, and (iv) a plurality of color tiles arranged in a set of four zones positioned among the first and the second set of tiles. Each zone includes a first and a second color tile, each having a HEX value representing a color different from (i) the first set, (ii) the second set, and (iii) the plurality of skin-toned tiles. The first and the second color tile are positioned non-adjacent to each other such that an angle measured between an outer-inside corner of both color tiles and a center point of an aperture ranges from 30° to 60°.
