In the following grid, the numbers from 1 to 6 occur only once per row, per column, or per colored rectangle. Given the relations between numbers and a single number to get you started, can you complete the grid?

Here's the correct sequence:

 

6 4 3 1 2 5

1 5 2 4 3 6

4 6 1 2 5 3

3 2 5 6 1 4

2 3 4 5 6 1

5 1 6 3 4 2
