Normal Sudoku rules apply.
A digit X in a circle indicates how many circles of the same color do not contain an X.

Setter's Note: after publishing this, I was made aware that an "anti-counting" rule has been used before! To the best of my knowledge, it first appeared in this puzzle by VikingPrime.
Solution code: Row 1

Took a moment to reorient the brain for "anti-counting" but flows so smoothly once understood.

Not to hard once you get your head wrapped around the inverted nature of the anti-circle rule. Great puzzle!
