This time you are mixing light (additive mixing) instead of ink (subtractive mixing).
This means many mixing operations will not change the color: e.g. when you drop red on yellow, the result will still be yellow.
When the resulting color is white, a new rectangle will be stacked on top of the white rectangle.
You win 10 points when you clear 2 rectangles in 1 operation.
