1. A system comprising: networking hardware to receive from a device to which the networking hardware is communicatively connected one 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: if the networking hardware receives the digital image and not the corrected optical property value, determine the corrected optical property value based on the physical optical property calibration chart and the optical property of interest within the digital image; 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.
