You might be technically correct, but if you extend that logic, why not just make the grid 1x1 and select a single color? The grid size is part of the pattern in the same way that the colors are part of the pattern. It’s not just a color pattern, it’s a generalized mapping of input to output. In short: you need to resize the grid because that’s what the examples do. |

For two reasons:
1. The initially suggested grid size was 3x3.
2. Filling in a 3x3 grid is sufficient to show that you understood the pattern, but filling in a 1x1 (or even 2x2) grid is insufficient.
Requiring the user fill in a larger grid is a waste of time. The existence of the grid size selector would still make sense in cases where a 2x2 grid would be sufficient to show the solution, so it is not obvious at all that a 6x6 grid should be chosen.

To understand a pattern, you have to see at least two valid inputs and corresponding outputs. For the first example, a valid example for the expected output grid size is missing.
I arrived at the "correct" conclusion eventually, but the only indicator was that the reading direction for the UI was absolutely ridiculous ( https://i.imgur.com/CuQ2z2N.png ), suggesting that the authors did not think this through properly, so the solution had to be weird as well.
