Politely suggesting that false has some negative connotations, perhaps "artificial" would be a better word... or even illustrative or representational.
Fair enough. Then it's really a matter of intended audience. It is a correct technical term for the color-domain educated audience. Could be that I'm one of the few outside that audience, but probably not :).
The wikipedia article does note that pseudo-color is an alternative, and that carries less generally negative connotation.
This is all nitpicking anyway, but thanks for the bit of education!
[added - although now I can pick at the definition of "true color", since it is based on the idea of how a color would appaer to a human viewer. We know pretty well that there's quite a variance of perception of color amongst humans, so there arguably is no "true color". There's just X% of people see this color. :) ]
Perhaps it's like most other things in life. In hindsight, we might have done it differently.
In this case, there are probably better, more descriptive (and less confusing) adjectives than "fictitious" which would succinctly describe a non-existent but perceived (or imagined) force.
Even so, I never visualized something pushing me back into the seat. I always visualized the seat pressing against me. After all, I didn't feel sensations on the front of my body when accelerating. The sensations are the same as if someone has come from behind and starting pushing you.
Removing yourself from the equation makes it easier to see: imagine a ball on a string in a car. Something happens and the ball moves forward relative to you. It’s not hard to see how you might assume a force pushed the ball forward.
