Final answer:
Violet is the color most likely to be outside the CMYK gamut.
Step-by-step explanation:
The color that is most likely to be outside the CMYK gamut is violet.
The CMYK color model is used for printing and represents the primary colors of cyan, magenta, yellow, and black. These colors are created by subtracting light from white. Since violet is not one of the primary colors in the CMYK model, it is less likely to be accurately reproduced in the printing process.
Additionally, violet has a shorter wavelength and higher frequency compared to other colors in the visible spectrum, making it more prone to distortion and inaccuracies in printing.
