Final answer:
Photoshop will show 'Out of color range' when a specific color cannot be printed due to it being outside the printer's color spectrum.
Step-by-step explanation:
When attempting to print a color that cannot be accurately reproduced on a specific printer, Adobe Photoshop will typically display an error message indicating that the color is out of range. The correct answer is: a) Out of color range. This means that the color you are trying to print is not within the printable gamut (color spectrum) of the printer. It is important to use colors that are within the printable color range of the printer to avoid such errors. Photoshop offers several tools to help adjust colors to fit within a printer's capabilities, such as the 'Gamut Warning' feature.
