I think you are overly optimistic and forget a few key facts here.
According to wiki, 8% of males and 0.5% of female suffer from colorblindness. That means for the rest of the people, the color is part of the information that our brain use subconsciously when we go and grab a bag of Calbee.
Will it affect the Japanese general public? Minor inconvenience for sure. Will it affect sales? Probably for area popular by tourist? Maybe it move the needle by 1%?
But what's important that's below the fold is there could be other knock on effect as naphtha is used to make other product.
FYI, those 8% of males / 0.5% females stats are not about complete colorblindness, so almost all of those people use color in their life
Yes for men mostly it’s red/green colorblindness. It’s one reason traffic lights have a uniform order and why you might get tested on which light means stop and not what color on a written test in the US.
