This is the 4th puzzle in the Colorguru Chaos Deconstruction series, again in a small 9x9 grid. You can find the earlier entries in the series in my list of puzzles here

Rules:

Some cells in the grid have been colored. The given cells are also labelled with a letter representing the color: b - blue, g - green, p - purple, r - red, y - yellow

Using those 5 colors, color some more cells in the grid to satisfy the following conditions:

Every colored cell must belong to a Block. A Block consists of 1 to 5 orthogonally connected cells of the same color. Blocks of the same color OR SIZE cannot touch orthogonally or diagonally. NOTE: the size restriction here is new and different from previous puzzles in the series.

Every Block belongs to a Region. A Region consists of 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 separated by a white dot must be colored with different colors, and the sizes of their Blocks must be consecutive.

Cells separated by a black dot must be colored with different colors, and the sizes of their Blocks must be in a 1:2 ratio.
