I'm well aware of this, actually eo is even simpler in this case.
What I mind is having to do it too frequently and the fact
that promoting attribute from a symbol loses the color information:
would it be so inconvenient to have the color preserved by promotion?

When I add a visible attribute to a symbol, it is initially set with
a default color, fair enough, which I can edit in the symbol. What 
happens is that the automatic promotion (this is a visible attribute,
so it is always promoted) resets color to its default value for 
attributes instead of inheriting it. I think that this is a bug: 
if I change it explicitly in the symbol, it is because I have
a reason for it and it should be inherited.

Indeed. I think I did not express myself well, what I'd like is
inheritance of attribute color on symbols, perhaps even under
the control of a setting in the gedarc/gschemrc files.
