If I change color in palette color of object does not change accordingly

Hi,

I created a new document and added a square (fill color green) and a circle (fill color red).
Then I went to WIndows->Color palette->Palette editor. Now I changed the red color to a pinkish one. But the red circle keeps red and does not turn to pinkish as I changed.

Why the circle does not turn pinkish if I change it's color in the palette?.

I made a short screencast to show what I mean:

I know I can use 'Find and replace' to replace a color. But what I want to get is to change maybe 50 colors in my document. Calling 50 times 'Find and replace' is really annoying.
So I just wanted to change the color in the palette and wanted to change the objects as well - how can I get this?


Thanks...
