What intentions can and cannot do, part I

Suppose that law makers passed a law that demanded all $100 bills be printed in blue ink. But further suppose that those law makers, in passing this law, really intended that all $100 bills be printed in red ink. Would it be a false interpretation of the law to rule that printing $100 bills in blue ink was in keeping with the law, while printing $100 bills in red ink was a violation of the law? Do the intentions of the law makes force "blue" to mean red?
