2 color Japanese Sum Sudoku rules apply (Yes, this is my variation!) 2 colors will be used. Totals outside the grid give the sum of shaded cells. Colorful clues mean that all the clues in that row/column are the same color. Black clues mean that the clues in that row/column contain different colors. Consecutive groups must be separated by an unshaded cell when the groups are the same color. When the groups are different colors, no unshaded cell is necessary between them.
Anti-Knight rule applies.
Solution code: Row 1 Column 9

I stumbled upon some deadly patterns that I couldn't resolve no matter what. I got a lot easier after I realised that the german version did not mention the anti-knight rule. You might want to add this information.
Otherwise a very nice puzzle, as usual from you. :)
Panthera: I had someone translate it for me. Thanks for the heads up . I'll use a translator to add in that line!

Very nice variation!
A few statements about the rules that may allay any doubts for future solvers:
1. Each cell has 3 options: blue or red or unshaded.
2. Clues outside a row/column indicate the totals of all blue and red groups in that row/column.
3. A row/column with red clues cannot have blue cells in it, and vice versa.
4. For each row/column with black clues, at least one clue must be for a blue group and at least one clue must be for a red group.

You say "... must be separated by an unshaded cell when the groups are the same color". Should that say AT LEAST one unshaded cell? Or is at always just one?
At least 1. Thank you for asking!

You can watch the live solve on Rangsk's livestream #20: https://youtu.be/q7XT970lndk
Also to clarify, each black number must have a red and a blue clue in it, but it can be something like blue, red, unshaded, red
