Method for examining an article being inspected by using a vision system, wherein - the article is marked by applying a color area (26A-29A, 30A-32A) onto the article to identify particular characteristics of the article for recognition by an operator of the vision system, wherein the particular characteristics are indicated by a primary color that defines the color area (26A-29A, 30A-32A), - a camera of the vision system obtains images of the article including the color area (26A-29A, 30A-32A), - a processor of the vision system receives the images from the camera through an image infeed, - the processor processes the image infeed to identify the primary color and the presence of the color area (26A-29A, 30A-32A) and evaluate the primary color relative to a programmed target color to determine that an acceptable color is present in the color area (26A-29A, 30A-32A), and if so, the processor alters remaining areas of the image infeed other than the color area (26A-29A, 30A-32A) to generate a processed image containing the color area (26A-29A, 30A-32A), - the processor feeds said processed image output to an input on a display device which includes a display screen, - the processor displays the processed image on the screen with the color area (26A-29A, 30A-32A) displayed in the primary color or a shade thereof so that it is viewable by the operator for visual identification of the primary color by the operator, and - during said processing of the image infeed, the processor removes or reduces all of the remaining areas, including any distracting features of the infeed image received from the camera other than the color area (26A-29A, 30A-32A) to generate the processed image, wherein the processed image emphasizes the color area (26A-29A, 30A-32A) displayed on the screen in comparison to the remaining areas which are deemphasized to assist the operator in identifying the particular characteristics of the article indicated by the primary color for reducing eye fatigue of the operator. - the article is marked by applying a color area (26A-29A, 30A-32A) onto the article to identify particular characteristics of the article for recognition by an operator of the vision system, wherein the particular characteristics are indicated by a primary color that defines the color area (26A-29A, 30A-32A), - a camera of the vision system obtains images of the article including the color area (26A-29A, 30A-32A), - a processor of the vision system receives the images from the camera through an image infeed, - the processor processes the image infeed to identify the primary color and the presence of the color area (26A-29A, 30A-32A) and evaluate the primary color relative to a programmed target color to determine that an acceptable color is present in the color area (26A-29A, 30A-32A), and if so, the processor alters remaining areas of the image infeed other than the color area (26A-29A, 30A-32A) to generate a processed image containing the color area (26A-29A, 30A-32A), - the processor feeds said processed image output to an input on a display device which includes a display screen, - the processor displays the processed image on the screen with the color area (26A-29A, 30A-32A) displayed in the primary color or a shade thereof so that it is viewable by the operator for visual identification of the primary color by the operator, and - during said processing of the image infeed, the processor removes or reduces all of the remaining areas, including any distracting features of the infeed image received from the camera other than the color area (26A-29A, 30A-32A) to generate the processed image, wherein the processed image emphasizes the color area (26A-29A, 30A-32A) displayed on the screen in comparison to the remaining areas which are deemphasized to assist the operator in identifying the particular characteristics of the article indicated by the primary color for reducing eye fatigue of the operator.
