This image, originating from *The Theory and Practice of Colour* by Bonnie E. Snow and Hugo B. Froehlich (1918), represents a thoughtful exploration of colour theory during the early 20th century. The diagram presents a harmonious arrangement of hues alongside their lighter tints, capturing a systematic approach to understanding chromatic relationships and their aesthetic applications. Such educational visuals were essential in the burgeoning push for teaching art and design principles systematically, coinciding with the Arts and Crafts movement’s ideals of uniting beauty with function.
Incorporating both scientific inquiry and artistic sensibilities, this piece reflects a period when colour theory was gaining prominence not only among artists but also within the spheres of industrial design and education. It symbolises the way these ideas were formalised into accessible visual tools, offering a glimpse into an era deeply devoted to understanding the mechanics of visual language.
