Looking at this again, it doesn't seem very illustrative.

What I mean is that if you're going to assign an action verb like  
sprayPaint, there should be some reason that it's =not= "color", i.e,  
that it reflects some other aspect of the process besides changing the  
color. For example,

car color: #red.

says to me, "the color is red, whatever it was before is no more." We're  
divorcing the code from physical reality (which is perfectly fine and  
usual in most cases).

Other action verbs should be indicative of either the logical process we  
want the client to be aware of or a physical reality that we're modeling
