The original OP-1 uses color to give physical controls a clear role
Design archive: Teenage Engineering’s portable instrument shows how a few colored encoders can organize a dense set of functions.

A small set of recognizable controls
Teenage Engineering describes the original OP-1 as a portable synthesizer, sampler and controller. Its product page calls attention to four colored encoders and a color-coded interface. Those controls provide a useful reference for anyone deciding how much of a device’s operation should remain physically visible. This archival sample concerns the original OP-1, not the later OP-1 field and not a newly announced model.
Color with a job to do
In the accompanying photograph, the encoders stand out against the pale enclosure and repeated keys. Our reading is that color supplies a hierarchy: the important variable controls become easier to pick out without making every surface compete for attention. That is a visual interpretation. The manufacturer’s intent to make the interface intuitive does not establish that all users will find it easy, and we have not performed a usability test.
Take the principle, not the silhouette
For a desktop-device brief, ask which actions deserve persistent physical controls and which visual distinctions help the user recognize them. A restrained palette can still carry information. The useful lesson is the relationship between color, repetition and control placement—not a reason to reproduce another company’s industrial design.
