Rules:

Colorguru rules apply: Some cells in the grid have been colored blue, green, purple, red or yellow. Using those 5 colors, color some more cells in the grid. Every colored cell belongs to a Block, which is 1 to 5 orthogonally connected cells of the same color. Blocks of the same color or size cannot touch orthogonally or diagonally. Every Block belongs to a Region, which is 2 or more orthogonally connected Blocks. Blocks within a Region cannot be the same color or size. Regions may not touch orthogonally. Regions that touch diagonally have at most one color in common.

Cells with one or more arrows must be colored and indicate other cells of the same color X cells away in the directions of each arrow, where X is the size of the block containing the arrow.
