Another method, intended not only for the painter, but also for the interior designer, was published by Pedro J. Lemos around the same time.
The color designer can choose from six “color harmony dials” that can be placed over the wheel and rotated, revealing families of colors.

Lemos used a color wheel with lighter tints on the outside and darker shades on the inside. As a result, the colors visible within the dials include tints and shades, but lack any real deliberate choice of relative chroma or intermediate mixtures.
