Switching/altering multiple colors/hues in a group of objects?

[eobet]

Let's say I have a group with three of four shades of a color (really three of four different colors, as I haven't used any features beyond the color palette to get them).

Now I multiply this group, and what to change the hue (or contrast perhaps). In other words, I want to use the exact same modification/transformation on all four colors.

How can I accomplish this?

I have heard some mention of the "name gallery", but I couldn't figure it out (I'm used to the hue/value sliders in Photoshop, and lately, the Live Color dialog in Illustrator).

Using named colours to begin with will allow this kind of colour editing.

Have a look at this Xara Xone Workbook

Ok, so I've named every color in my object, cloned it a couple of times, and now I wish to turn one of the cloned objects into green, but have the others remain red.

How do I accomplish this, please?

Click an unamed colour on the colour bar.

Having the object I wish to change the color on selected first, I presume?

That turned the entire object into that color, removing all my gradients, and I have quite a lot of them, and would like to retain them, please.

EDIT:

I'm now replacing the colors in each individual gradient manually. The trouble is, when I select a gradient color point, it says "local fill color" color editor instead of the named color, and the color toolbar in the bottom only highlights the end gradient color points, not the middle ones, so I not only must I find each point manually, I now have to visually indentify which specific hue (out of five) I'm blending as well...

The only way to get what you want is to have a group of diferent named colors for each object.
For example:
green A
red A
yellow A
for group of objects A

green B
red B
yellow C
for group of objects B

This would be easy if Xtreme allowed to copy/duplicate a group of selected colors, but it doesn´t, so you have to manually duplicate all the colors you use and assign them to the group of objects you want to be diferent. This way you can get exact same modification/transformation on all.

If you use the same group of named colors for all of your groups of objects, every time you change one of the named colors all groups of objects will change accordingly.

Hope this makes sense.
