the idea originates in the "Colour 500-Series Palette" audio circuit in the API 500 form factor which is used in recording studios. It can house up to three Colours which are individual aidio processors which colour the sound and have different behavoiurs, depending on the circuit. Some have the saturation behaviour of CMOS chips, other that of JFETs, some add the special sound of transformers. Other Colours recreate the sound of vintage audio gear like compressors or simulate tape delays.
Black Market Modular not only brings this idea into Eurorack world but enhances it with voltage controlled level and individual usability of each Colour.
It goes even further: In future there will be Colours with voltage controllable parameters (the so-called ColorCVs) that can be assigned to the four CV inputs. It can be very interesting if a number of parameters on different Colours have been assigned to the same CTRL CV-input.
Each section of the module has individual signal in- and outputs but there's also a sum output where each Colour is mixed with 1/3 of it's level.

CTRL CV inputs A-D
