Graphic guidelines for the next release

[Robin Trew]

In case too many potential users of Ver 3 find it visually a little 
fatiguing, and decide to stick with Ver 2, a useful source of graphic 
guidelines for any redrafts is, of course:

Edward R. Tufte, "Envisioning Information", Graphics Press.

One useful rule of thumb which it expands on (in relation to visual 
contrasts) is that using the "minimum effective difference" will 
usually optimize the signal / noise ratio.

Redundant contrasts, or contrasts which are stronger than required, are 
pretty much like distracting noise, or excessive volume - they aborb 
precious mental resources, and make it harder to concentrate.

The problem is often, of course, that marketing departments want to 
"catch attention", and cry their wares as loudly as possible.

Good luck !
