The colors are lovely but when I look I see very large L-s. I think the red color takes away from the illusion affect that the grey has. So it depends on what you are after.
I made a mystery quilt one time and it was supposed to have the illusion affect but I did not know that and was not told when making the quilt. Because of that I have a nice quilt but it misses the illusion and 3 D feel.
