Now imagine that one of those 100 pixels is almost, but not quite, the same colour. That's going to need more space to describe. Still not as much as storing all the original values, but more that the compressed version. If you ignore that different pixel, and pretend it's the same colour as the other 99, you don't need to use the extra space. In other words you've given up a small amount of the original data in trade for an even smaller file. ======== Thanks. Hmmmm.
