Build a checkerboard For this challenge you will print the coordinates and color of each piece at the start of a game of checkers. 

Enter the x and y (comma seperated) for every square (indexed 0-7) on a checkerboard, followed by a "r" or "b" (for red or black) where the top of the board (closer to y=0) is red and the bottom is black. newlines between pieces are required and no spaces are necessary.

This is code-golf so answers are scored in bytes with fewer bytes being better.

Trailing newlines are allowed but not necessary and the order must be exactly of that below.

Desired output:

0,0r
0,2r
0,4r
0,6r
1,1r
1,3r
1,5r
