[ubuntu-art] Dialogs icon and tangerine

[Josué Alcalde González]

Last update of tangerine has included some new icons for dialog actions.

The icons included in last update use this metaphor:

with a red close icon.

The icons are:
- cancel: a yellow rounded back arrow 
- apply: a green v
- yes: ?
- no: ?
- close: a red x
- accept: a blue intro icon

I have made the needed links and I have seen some problems:

The close icon is red. It is used in a lot of places (tabs for gedit,
epiphany and console, close button in notifications, close in lists...)
I think red doesn't fit very well in those places, but the biggest
problem is that it is resized and looks very bad in epiphany and
console, and worst in gedit and notifications bubbles.

Why the close icon should be red? Why is it better than dark grey?

I have also see this unofficial tango icon, which has a different
similar metaphor for cancel but different for apply.

They looks great for me, red to cancel and green to apply, like most of
systems, and with a better metaphor for apply than the traditional v. It
is similar to cancel arrow, but with the arrow in the other direction.

Finally, I would like to do a proposition:
- cancel: a red rounded back arrow 
- apply: a green rounded forward arrow
- yes: a green v
- no: a red x
- close: a black/dark gray x
- accept: a blue intro icon (perhaps orange or green)
