1. A system comprising: networking hardware to receive from a device to which the networking hardware is communicatively connected one or more of: a digital image of a physical scene including an optical property of interest and a physical optical property calibration chart; a corrected optical property value of the optical property of interest determined based on the physical optical property calibration chart and the optical property of interest within the digital image; a processor; and a non-transitory computer-readable data storage medium storing computer-readable code executable by the processor to: determine a search query based on the corrected optical property value; search a database using the search query to determine search results for the search query that have appearance attributes with optical properties at least similar to the corrected optical value; and return the search results to the device via the networking hardware.
