Does anyone know about Idioms
He was angry. Red is an "angry" color, and the color of blood.
I think it has something to do with bulls. There's a myth that bulls charge everything red.
Don't trust it. MAYBE that is due to old marketplace vendors selling moist goods such as meat, where salt was added to help remove bad taste and prevent some disease.
Salt is symbolic for intelligence.

7. Sharp lively wit.
The real meaning should be something like "put a little thought in it" (NTs have to remind themselves to actually think), which further interpretated means effectually "don't trust it".
Some you just have to learn and even they have uncertain origins.
It is cold enough to freeze the balls off a brass monkey
To take issue with people who don't know them is pretentious. Same goes for metaphors. People behave like they've always been understood when they come from a historical context. I would say they are just convoluted symbolism only the original context which they were written/said is no longer there. Anyway people prefer similes. 9/10 if you ask somebody to come up with metaphors they will give you similes.
How could rain be compared to cats and dogs? There is nothing remotely similar about them and NTs know this.
Simile: Deaf as a post. As post don't hear and are obviously inanimate. But animals are not inanimate so this could cause confusion.
Dead as a door nail:
But why particularly a doornail, rather than just any old nail? Could it be because of the repetition of sounds, and the much better rhythm of the phrase compared with the version without door? Almost certainly the euphony has caused the phrase to survive longer than the alternatives I’ve quoted. But could there something special about a doornail?
The usual reason given is that a doornail was one of the heavy studded nails on the outside of a medieval door, or possibly that the phrase refers to the particularly big one on which the knocker rested. A doornail, because of its size and probable antiquity, would seem dead enough for any proverb; the one on which the knocker sat might be thought particularly dead because of the number of times it had been knocked on the head.
But William and Mary Morris, in The Morris Dictionary of Word and Phrase Origins, quote a correspondent who points out that it could come from a standard term in carpentry. If you hammer a nail through a piece of timber and then flatten the end over on the inside so it can’t be removed again (a technique called clinching), the nail is said to be dead, because you can’t use it again. Doornails would very probably have been subjected to this treatment to give extra strength in the years before screws were available. So they were dead because they’d been clinched. It sounds plausible, but whether it’s right or not we will probably never know.
"Not enough room to swing a cat," referring to a very small space, refers to a "cat o' nine tails," which used to be used to whip people.
"Let the cat out of the bag"-At old time county fairs, they used to place pigs in bags to take them to market. Some jokester would place a cat in the bag instead. The person receiving it would open the bag to discover the cat, thereby letting the cat out of the bag, and the secret was revealed.
I get metaphors and figurative speech when it’s used by people in fiction.... Most everything I write and think is figurative to some extent.
I like “hang tough”; though I don’t know the original meaning, I always assumed it was alluding to “keeping your chin up” when your neck is in the noose at the gallows, and being resolved in your fate.
