• This is my second puzzle on a variant of the puzzle "Tasukuea".

Apply Tasukuea rules : Shade cells according to the following rules :

• Shaded cells must form squares of any size.
• Black squares can only touch diagonnally.
• Clues cannot be shaded and are treated as white cells.
• Clues represent the number of black cells adjacent to it. Ergo, a 13 clue is fulfilled if it is adjacent to a 2x2 black square + a 3x3 black square (4+9).
• In the solved puzzle, white cells must form a unique field (all white cells are linked orthogonally).
• A ? represent a number greater than 0.

This puzzle uses a variant called "Color Tasukuea". Here are the additionnal rules :

• All uncolored ? hold different values. This value can appear as an explicit clue in the puzzle (a shown 2 clue doesn't refrain one of the ? to also be a 2).
• Colors are associated with a unique number (different colors are different numbers). For each color, all arrows are stated and all clues are colored if they hold the same value as the color. If no color is stated on a clue, then it cannot hold the same value as any color in the grid.
• Arrows point at a row or column. Its value/color represents the number of shaded cells in the pointed row/column (e.g. If green=6, then all rows/column with exactly 6 shaded squares will have a green arrow).
