Two-Doku Xtreme

This is a more difficult follow-up to my Two-Doku puzzle, found HERE

Rules:

Help! Someone has forced two sudoku puzzles into the one grid. I need you to place the digits 1-5 into each row, column and region TWICE!

• The cells must be filled with the numbers 1-5 such that a number occurs in a cell of a particular colour (Red/Blue) once in every row, column and region
• Furthermore, identical digits cannot be orthogonally adjacent
• The colour of each white cell must be determined
