How can I eye dropper a color??

Question

When I use the eye dropper it doesn't pick up a color, it picks up the setting of the object selected. So for example if I have two objects and the one on top has a style, a blend mode and opacity and where two areas of the two objects intersect I want to sample the resulting, exact color. Let's say the color is purple. When I eye dropper that point it picks up green, because that is the color of the object originally not after all the processing.

Answer 1

1. Draw a temporary object (rectangle, etc.)
2. Select the object(s) involved in the transparency stack from which you want to sample a color. Object>Rasterize.
3. Select the temporary object.
4. Eyedropper: Press and hold Shift while dragging about in the raster object. The temporary object's fill takes on the color under the cursor.
5. Edit>Cut the temporary object to the clipboard.
6. Edit>Undo until you have undone the rasterization of step 2.
7. Edit>Paste. The pasted copy of the temporary object will still have the fill color you sampled.
Simply holding Shift while sampling with the eyedropper enables it to pick up colors from grads or raster objects, but does not cause it to pick up the screen colors resulting from transparency effects. That's why the above-described steps involve a temporary rasterization of the objects involved. The reason for the temporary object is to work around the fact that Undo also undoes the Eyedropper step or the addition of a Swatch were you to try that before undoing the rasterization. Undo does not, however, undo a copy/cut of something to the clipboard.
Everything in Illustrator is a workaround.
