As always, your quilt, your rules. Traditionally, red is the center square of a log cabin as it represents the heart/hearth of the cabin. There are a variety of reds, you can always audition the different shades to see if any strike your eye. I have also seen "traditional" log cabins with the center square as a yellow to represent the "flames" of the hearth. If you are not making a "traditional" log cabin, there are many colors that go with/contrast with purple.
