Abstract: A color adjustment system for changing the color of fluid flowing from a source. The color adjustment system includes a main mixing pipe connected to storage vessels to continuously receive flows of colorants from the storage vessels. A fluid inspection cell is connected to the main mixing pipe for continuously receiving a sample portion of the flow of the fluid composition. A spectrophotometer is positioned to view the sample portion of the flow of the fluid composition through a window of the fluid inspection cell. The spectrophotometer transmits measured color values to a control unit, which generates control signals in response thereto. The control signals are transmitted to colorant pumps, which pump colorants to the main mixing pipe in response to the control signals.

Abstract: A production system for continuously producing a paint composition. The production system includes a main mixing pipe connected to storage vessels to continuously receive flows of paint components from the storage vessels. The flows of the paint components are mixed together in the main mixing pipe to form a continuous flow of a paint composition. A fluid inspection cell is connected to the main mixing pipe for continuously receiving a sample portion of the flow of the paint composition. A spectrophotometer is positioned to view the sample portion of the flow of the paint composition through a window of the fluid inspection cell. The spectrophotometer transmits measured color values to a control unit, which generates control signals in response thereto. The control signals are transmitted to colorant pumps, which pump colorants to the main mixing pipe in response to the control signals.
