Neon Screen

By chance, I saw a very interesting sudoku puzzle: neon screen, and I was immediately attracted to it. Later after searching on the Internet, I knew that it was a puzzle in the 12th CCBC competition. CCBC (Cipher and Code Breaking Competition) is a Puzzle Hunt competition about classical cipher. I studied it very devotedly for a few days and then I set a similar puzzle myself. If you happen to like this kind of puzzle, you can give it a try. However, it needs to be reminded that this puzzle is not very eye-friendly.

• Known numbers on the sudoku board are colored and blank cells are filled with color. the sudoku board is a combination of three monochrome boards: red, green, and blue.
• The red, green, and blue numbers on the sudoku board are the same as the numbers in the same position on the same color board.
• The numbers of the three colors of cyan, yellow and magenta are the sum of the numbers in the same position on the two monochrome boards, and the colors are also mixed.
• The blank cells do not have numbers, so their background color represents the color of the numbers.
• The color mixing rules are as follows:
  Cyan = Green + Blue
  Yellow = Red + Green
  Magenta = Red + Blue

For example, if C3 on the sudoku board is a green 5, it means that C3 on the green board is 5. If D6 on the sudoku board is a yellow 7, it means that the sum of D6 on the red board and D6 on the green board is 7.

Enjoy!
