This type of construction is acceptable; phrases or sentences formulated this way can be understood with no ambiguity; they are correct English.
However, they are rarely used and, as far as I know, aren't characteristic of any particular dialect of English. The type of sentence you show is almost always formulated in the order
subject is adjective
So the effect of the alternative construction:
adjective, subject is
is that it generally sounds very strange, although unambiguous and grammatically fine.
So, in fiction we find this type of adjective-first or verb-last (or both) construction deliberately being used in the speech of a character to mark out that character as unique or different from others. The classic example is Master Yoda in Star Wars:
Named must your fear be before banish it you can.
Truly wonderful the mind of a child is.
Difficult to see. Always in motion is the future.
Powerful you have become, the dark side I sense in you.
