How to Play Semaphore

You have to create a number with no repeating digits using the following color clues:

no digit can be used

one digit can be used if we change its position

one digit can be used as given

For example, from the following clues

1  8  7   ..

we learn that two of the digits of 187 belong to the number we are looking for, with one digit already in the correct position and the other in the wrong position.

The position of a color clue does not have to correspond to the position of the digit it refers to in the given string. More than one answer is possible!
