People on the Blue Lake is an oil-on-canvas painting executed in 1913 by the German artist August Macke.

The main colors of the painting are those obtained during the decomposition of white light: red, orange, yellow, green, blue and violet.

Freely, without sharp boundaries, they pass one into another, uniting in a kind of color circle with twelve sectors.

According to his wife Elizabeth Macke, August at that time was fascinated by the task of conveying dynamics in painting and its solution not through perspective construction, but through the use of the "play of shades" - this should happen even within the framework of one color, for example, green: "without a single red spot, the color should work, vibrate, live."

In his later paintings, the main principle was the liveliness of the integral perception of the work by the viewer, which was the result of only the mutual influence of colors, and not perspective or cut-off modeling.
