Rules
Spiral Galaxies: Divide the grid into regions of orthogonally connected cells. Each region must contain exactly one white dot and have 180° rotational symmetry around the dot.
Colors: Each region must be colored red, green, blue, or yellow. Some cells’ colors are given. Two regions of the same color may not touch along an edge.

Acknowledgments: This puzzle was set in celebration of Niverio’s birthday. The rule set was borrowed from Crispy16 (but no chaos/suguru, just the galaxies). Thanks, please enjoy!
Solution code: Row 5 left to right (b=blue, g=green, r=red, y=yellow, all lowercase).

The solution code says "all lower case" but upper case works too.
Oh, and fun puzzle btw :)

Loved it! I'm a sucker for both of these puzzle types.

A very nice puzzle, I really like galaxies!
By the way: you should better not mention 'all lowercase', because all letters are automatically converted to upper case when solvers enter solution codes. This could be irritating when entering a wrong solution.
From 'hints' under 'Create a new puzzle':
Solution codes may only contain letters, digits, and the following special characters: ! $ % & / ( ) = + - * # ~ < > |. All letters are automatically converted to upper case, and illegal characters are stripped from the solution code. (The same thing happens when solvers enter solution codes!)
