I'm not an expert in this matter, so AFAIK the most part of electronic components have numeric values while resistors and few other components have colors: why is that? Why there is not a standard for all electronic components establishing the use of values everywhere? I know there are a bunch of very interesting opinions out there (for example Why do resistors still use color coding?), so I'm not looking for one more "opinion" based on personal intuition or needs, but for something more, a kind of "Official" answer.
Would not it be better to have a unique standard method for indicating values of any kind of components expressing them the same way (using just numbers everywhere or just colors everywhere)?
I'm thinking to people that is color blind: isn't better to have just values indicated by numbers and letters to make them able once for all to not confuse a color with another? IMHO this would be in general a better way to go.
PS: If some one votes down please specify why exactly, thanks in advance.
