Clues outside the grid can be either for Japanese Sum Sudoku or Sandwich clues (with coloring)

Nonogram/Japanese Sum Sudoku rules apply. Sums are of shaded cells. If all the cells in a row or column are the same color, then the clue is that color as well. Any clue in black represents clues in more than one color (each grouping is a different clue, so 5 20 could mean a group of blue adding to 5 and a group of red adding to 20). A blank space is required between groups of the same color, but not between other colors.

Sandwich clues apply -- digits outside the grid may represent sandwich clues (between the 1 and 9) when shading the 1 and 9 are included in that group!

Example Clue: 3 4 6 could be simply a red 3, blue 4, space(s), blue 6, or red 3, blue 4, red 1 then red 5, OR it could be red 1, red 3, red 9, blue 4, red 6.. or any combination thereof.

To make the rules clearer (as suggested by Sktx)
1) the sandwich clues are ALSO nonogram clues.
2) If all the SHADED (or COLORED) cells in a row or column are the same color, then the clue is that color as well. (if only red was used in that row/column, then the clue is red. If only blue was used in that row/column, then the clue is blue.)
