Hello, I don't know if I'm alone in this, but the mask/clip options in vers x.x are very hard to use. The results are hard to predict. Colours of objects will change (depending on fore/back ground order etc).
I never had such problems: No color changes ever happened to me. You are probably not using it correctly - see explanation below.
Also, the difference between clip and mask is not clear.
In both clip and mask, you select two objects, and after applying clip or mask the result is that the lower object is clipped or masked by the upper one. In clip, it is constrained to the shape of the upper object, regardless of the upper object's color/opacity/blur properties. With mask, it is also influenced by the upper object's color like masks in photoshop or Gimp or Illustrator: Where there is a white color in the upper object, the lower will be opaque, and where there is black, it will be transparent. shades of gray (or shades of color) are semi-transparent depending on value. You can use a white-to-black gradient on the upper object to have a gradient mask. the opacity of the upper object is also taken into account, but you'd rather not use that and just use shades of gray. Blur also influences mask.
I come from a (distant) background in Macromedia Freehand and in that world they had a concept called "Paste Inside".
- Now that made perfect sense and was perfectly predictable. One did not have
to setup a bunch of "tests" on the side. 2. You could select items within the mask, and easily edit/move them.
In Inkscape 0.44, I get the feeling that those items are new and experimental, perhaps they will get a better user interface - I'm not sure where the coders are at now, I know they move really fast on a thousand fronts.
AFAIK In 0.45 (and perhaps current test versions) you will be able to do it, but you need to be in outline mode to see the clip or mask object.

I find the results of clipping very predictable. Masking maybe less so, but that's likely just because I tried it only briefly.
Maybe you didn't notice yet that the object that will be used as clipping path or mask has to be on top?
But I often want to clip objects that are entirely contained within the clipping path to then apply blur and have it not bleed outside the desired area. Arranging the smaller object below the clipping object is fiddly business.
Also, the difference between clip and mask is not clear.
Clipping means only the parts of the clipped object that are inside the clipping path will be rendered.
Mask does that too, but the defining aspect of it is that the lightness of the mask is used to determine the alpha of the resut, with black = 100%. Actualy it might be more complicated, as I only tried it with from black to white gradients :)

Paste Inside sounds like a very nice concept. Provided you can paste inside and In Place.
An Outliner that lists objects and shows clipping/masking/cloning relations would be helpful :)
