I think you need to relate this to the case here to establish the objective correctness the previous comment claims, in terms of the screen shots we're looking at. Ridiculous, of course, but that's my point -- we're arguing about feelings not facts.

Here, for example, the colors we're discussing are the toolbar icons in the screen shots. A lot of the colors are arbitrary, so don't really impart information. E.g, shapes are characteristically green, tables aren't characteristically yellow, charts aren't characteristically blue. So that's noise, not information. You can only hope that doesn't degrade the UI too much. The yellow sticky note, on the other hand, is characteristic, so does impart information, and the color wheel is perfect. So some good ones and some bad ones. Not clear at all it's good. Now, people who use the software a lot will come to learn arbitrary associations, but, of course, that goes for any arbitrary association.
