Color meanings with regard to buttons: Opinions/research?

One problem that has continually surfaced in my recent work at my place of employment has been button colors. Specifically, little or no thought goes into the meaning of what color is being used for the button in regard to its functionality. Even worse, there is often no thought given to a consistent treatment of buttons across an interface.

So for example, I'll see save buttons that are red, and I'll see the same color being used for a save, change and exit button.

Touch screen with buttons, drop-downs in touch screen

Hi !

This is my first posting here, I’ve enjoyed reading many discussions in the past, so be gentle :)

Nr 1. Right now we are discussing back and fourth the use of buttons in addition to touch screen. I should mention that we do not have strict accessibility requirements, it is not a product for open spaces, where all tactile feedback is important.

Ubuntu UX Change Battle Is a Great Forum For Impassioned IxD discussion

A recent article on Slashdot.org brought to light an internal batting raging on about changes to the button layout on one of the Ubuntu skins.  I found this really interesting because in reading the comments, you really get a sense of the arguments for and against changing a given feature in an overall design.  

The comments on the Ubuntu UX feature are here:

Next & previous button order

As discussed by LukeW in Web Form Design, it's best to have the primary
action of a form be the first button that the user sees. For left-to-right
languages this means having the primary action on the left and any secondary
actions on the right (see A in this illustration

Label alignment left or right?/Button alignment

Sylvania wrote:

Which OS(es) are you targeting?
On Windows, the general guideline is to left-align labels; on Mac,
labels should be right-aligned. These are guidelines, of course, and not
hard-set rules, but software tends to look more polished when it follows
the visual styles of the OS on which it runs.

Here's my question:
On a similar topic, what about buttons? Apple guidelines say to right
align the function that is mostly used (unless it is going to cause the
user to lose all their work), but on Windows it's the opposite.
