The color blue


We will be assigning a color from the light spectrum to each issue of the new Prism. Learn more about the color concept and the current focus color: blue.

Each issue of the new Prism will feature one focus topic. It will deal with issues that are relevant to every employee. We will examine the topic just like we would a prism, which is to say, from different angles, by looking at all of its facets. And to help the focus topic stand out visually, it will receive its own color from the light spectrum in each issue.

Digitalization: focus color blue

Why did we choose the color blue for the first issue of Prism, which focuses on the topic of digitalization? Blue is considered the color of innovation. It inspires creativity and finding new strategies for solutions. Canadian researchers were able to identify these effects in experimental cognitive tests. The researchers had their subjects complete various cognitive tests on a computer. The monitor's background was sometimes blue, sometimes red and sometimes white. The tests showed that the color blue enhanced creativity and fueled innovative ideas. The researchers concluded that blue fosters a sense of security, which encourages people to think outside the box.
