By Jeff Wajes
Divide the grid into 9 non-overlapping regions of orthogonally connected cells. Place the digits 1-9 exactly once into each row, column, and region.
Cells separated by a white dot contain consecutive digits. Cells separated by an orange dot contain digits with a difference of at least 4. Cells separated by any dot are in different regions. Not all dots are given.
Using red, green, and blue, color all circles such that:
-Orthogonally adjacent circles are different colors.
-The digit inside a circle appears that many times in circles of that color.
Huge thanks to FIT7Y and NXTMaster for testing!

Very rarely does a puzzle make me want to solve it all over again just to re-experience the beauty of its logic. This is one of those times. Thank you, Jeff!

One of the hardest I have ever solved. I am not even sure all my moves were legitimate but in the end it worked. How do you make such a beauty?

Crazy hard! Found the break-in and felt like the puzzle never relented. Fabulous setting!

A serious challenge which took some working out. Brilliantly done.
Snookerfan's advice on hydration very necessary - I had to work hard during the current heatwave.
