1. A method, comprising:
illuminating, by a processor of a scanner, Light Emitting Diodes (LEDs) to illuminate an object placed in a field of view of a lens of a scanner with light in a first spectrum;
filtering, by the processor of the scanner, the light with an amber filter during the illuminating and causing the object to be illuminated with filtered light in a second spectrum that is substantially devoid of blue light;
capturing, by an imaging sensor of the scanner, an object image of the object as reflected filtered light in the second spectrum;
performing, by the processor of the scanner, item recognition on the object from the object image by reading a barcode from the object using the reflected filtered light in the second spectrum while performing the item recognition;
passing, by the processor of the scanner, an item identifier for the object to a transaction terminal interface to the scanner based on the performing of the item recognition during a transaction for the object at a transaction terminal, wherein the transaction terminal is a self-service terminal or a point-of-sale terminal; and
improving a user experience by removing a glaring blue light component of the white LEDs illumination while not impacting performance of the item recognition when processed for the transaction being conducted at the transaction terminal that is interfaced to the scanner.
