Is it just me or is there a color difference between this tile and the left tile? Other than that it's a very good job.

I'm not sure what it is, but I notice a LOT of tile previews show that. I wonder if it's a particular software some folks are using, or file format they are uploading.

I used PS 5.5 for all but my most recent two (which are both PS 6.0)... and I turn in PNGs. Could it be JPG entries? Paintshop Pro entries?
