If everyone wants to use a cream color, that's fine with me. :-)
In a swap sampler quilt often the backgrounds are not the same for every block. Backgrounds look nice with a fabric that is a blender, a solid, a tone on tone, or a small print that reads as one color... Variety can be nice! :-) Anyway, color is interpreted differently by individuals.
The reply box on this page looks cream to me. The post ends up on a background of what looks like dark cream. The 'blog this post, reply, reply with quote' line looks like a very pale tan, and the line with the date on it looks light tan. But my monitor may have way different shades of color than yours! And what I think looks like tan may seem cream to you and vice versa! :-)
