A comprehensive color reference chart displays hundreds of hue samples arranged in orderly columns, each labeled with precise nomenclature and accompanied by descriptive text detailing botanical and natural sources. The palette spans from deep blacks and grays through jewel tones of blue, green, and red to warm ochres and pale creams, creating a methodical visual taxonomy rendered in a classical reference-chart style. Built from double-wall stainless steel and made to order, holding 20 ounces with a snap-on lid, a standard-cup-holder fit, and wraparound artwork. Your commute carrying original art instead of another branded tumbler.
