Systems and methods for color selection are provided. A web server stores a lookup table that associates room types and types of feelings with paint colors such that each possible combination of room type and type of feeling is associated with a subset of paint colors. A user device displays the room types, receives a room type selection indicating a particular room type, displays the types of feelings, receives a type of feeling selection indicating a particular type of feeling, accesses the lookup table and determines the associated subset of paint colors in the lookup table for the combination of the particular room type and the particular type of feeling, and displays the associated subset of paint colors as recommended paint colors for the combination of the particular room type and the particular type of feeling on the display of the user device.

The present disclosure relates to a measuring apparatus for analyzing a measuring medium. The measuring apparatus includes a probe housing, a radiation source, and coupling and decoupling optics. The optics have a measurement window in the probe housing to direct radiation of the radiation source into a measuring region outside the probe housing and including the measuring medium, and to block measuring radiation from the measuring region. Via the optics, a receiving device detects measuring radiation and generates output data. An additional physical or chemical sensor is integrated into the probe housing and is designed to detect a measurand of the measuring medium and output measurement signals. An electronic measurement unit is configured to collect and process the output data of the receiving device and the measurement signals of the additional physical or chemical sensor.

Certain examples relate to emulating a spectral measurement device in a color measurement apparatus. In these examples, a primary spectral measurement device measures a first spectral characteristic of a rendered color output. A predictive model, parametrized by parameter values, is applied to the measurement from the primary spectral measurement device to determine a predicted measurement of a second spectral characteristic of the rendered color output which would be measured by an ancillary spectral measurement device. Parameter values are generated by training the predictive model with data from the primary spectral measurement device and the ancillary spectral measurement device.

A medication assurance system for verification of both the medication and the patient is disclosed. A portable spectrometer is used to obtain a light spectrum of the medication. A subject identification or biometric device is used to identify the patient. A controller coupled to the portable spectrometer and the subject identification device identifies the medication by performing a chemometric analysis of the light spectrum. Based on the medication identified and the patient identified, the controller can determine if the medication is to be taken by the patient.
