Lighten Up

Title: Lighten Up

Rating: 2/5

Given the desire to have a puzzle where the colors steadily faded as one travels inward, there are lots of un-twisty regions.  Hence the easier rating.

The official rules:

• The digits 1 through 9 appear in each row and each column exactly once.
• Digits in each shaded region must multiply to the indicated product.   
• Squares with multiple colors contain a number that’s used in the product for adjacent regions of each of those colors.  
• Remember: numbers can repeat within a shaded region if that doesn't violate the first rule.
