I thought the following rule was set in stone: don't use 'and' between a pair of adjectives preceding a noun:
However, someone in the comments on the following question disagrees, saying: it's not a hard rule, it's a matter of style, and here are some examples to back it up.

I thought to get confirmation and a second opinion.
EDIT 1
It can probably be generalized to a list
Is it better to list adjectives, with an "and"?
EDIT 2
Thanks for confirming what @Lambie said. I have to admit that
It involves a technological, theoretical challenge
didn't sound so good, or at least
It involves a technological and theoretical challenge
sounded better (in the first place).
Moreover, the link that I supplied does say in the beginning that there are exceptions such as a black and white shirt.
EDIT 3
Regarding the suggested link
Commas for multiple adjectives
It suggests a test for coordinate adjectives. First, the test of replacing the comma with an 'and' doesn't clearly say (like @Anton confirmed) that it's a correct option that can be used (until @Lambie corrected me, I thought you can't use 'and' at all). In both cases, it says you shouldn't.
Moreover, according to the test, both of my examples
- It involves a technological and theoretical challenge.
- He wore a black and white shirt.
fulfill the coordinate adjective test, and the link says that comma should be used instead of 'and'. I believe this to be incorrect.
If I had to guess, I think the rule might be related to the order of adjectives:
https://dictionary.cambridge.org/grammar/british-grammar/adjectives-order
If the adjectives belong to the same category, then they would naturally pass the coordinate adjective test. However, since they belong to the same category, 'and' should be used instead of a comma. At least I think it applies to my two examples above.
