Question

True-Blue very loyal, dependable, and faithful

Accepted Answer

The true-blue supporters of our team cheer for us even when we lose. This expression comes from an old proverb and has at least two possible origins. In the 17th century, blue was the color of many British groups: Scottish Covenanters, the Whig party, and even the varsity teams at Oxford and Cambridge universities. Anyone loyal and true to those groups wore something blue. Blue was also known as a true color because the blue thread made in Coventry, England, during the Middle Ages was highly regarded for holding its color. The blue dye didn't run, and so blue came to stand for faithfulness. Note also that "true" and "blue" rhyme, and rhymes often help an idiom become more widely used.
