Forbidden pattern
If you see a pattern above the puzzles that has a purple background, you must fill your grid so that this pattern does NOT appear anywhere.
The part of the pattern that are not colored (like the top-left and bottom-right corner of this one) are not part of the forbidden pattern and can take any color.
For example, here we know that this cell cannot be black because the cell in its bottom-left corner is white and this pattern is forbidden.
Following the same logic, we know that all these cells must be white too.
Here is another example: this cell already has "black then white" cells bellow it so it cannot be black.
