Spatial RGB Knob

Thought about leveraging the third dimension (depth) and stacking several different sliders to get multimode input in a compact form.

This approach works well with naturally distinguished properties like RGB channels that are easy to visualize based on their innate semantic traits (color coding, in our case: red channel represented by red, green by green, etc.) to quickly identify in which mode you are.

Another example is a controller for cold/hot water. It can be a good candidate for this type of interaction since cold/hot labeling has a strong convention around its semantics (red for hot, blue for cold).
