I've told some people this and some people this have already figured it out. I'll draw diagrams when i have time.
So pen without insert have more momentum then pen with insert. Here's an easy way to put it,"Would you spin a Bictory with solders in the middle of the pen or a Bictory with Solders on both end of the pen?"
Momentum = Weight X Speed Both end of the pen are moving at a greater distance than the center, plus most pen's weight are at the end.
Light and Spectrum
Black absorbs the light while white reflects light. God this gonna be hard to explain.
Take a comssa and spin it. Then take a Bictory with Black caps and white barrel and spin. Which has better effect? White has better effect then black, duh.(I'll get to the effect of colors later.)
Now to enchance the effect, use a black background underneath the comssa. With the light shining onto the pen(for better effect, try not to shine on the black background) you have a bright reflective white while black is absorbing the light.
The more dark and the less bright will make the bright's effect more visible.
Now for colors. You have to indentify which color is dark and which color is bright. Blue is dark compared to Red(profile grips on comssa we're talking about). Have you every tried spinning something like a g-ryzer and the blue doesn't seem to stand out as much as red? That's because black is absorbing more light spectrum rather then reflecting more light spectrum like Red.
G-ryzer would be a perfect example of my theory. Weights are at the end(metals tips in caps), empty barrel in the middle, black barrel, and colored caps interrupted with white grip/tape in the middle of the cap.
I don't feel like typing so I'll answer your question and edit this post. -

thats really true but if you think about it light colors are also eyecatching which focases the brain on the colors=P

You seem to have started the post asking about inserts' momentum somehow, then moved into barrel colors and filming/viewing...
I don't know the actual point of the thread, so I'll just throw out a few ideas based on various parts of your post. 
Barrel Colors:
It seems to me to simply be a matter of matching the pen to the background. The backaround should generally be opposite the ends of the mod. A Comssa mod over a black BG looks great as long as the very ends of the caps are visible, you can still see where the ends are located. Spinning it over a white background doesn't look as good due to less contrast to the ends of the mod. Similarly, a basic BICtory with black caps looks awful over a dark background because the caps can become invisble, especially on camera.
Inserts and Color Matching:
I only regard barrel inserts as far as matching the barrel to the ends of the mod. Again, the ends and the background contrast are most important to me when filming. You need the contrast.
Insert Weight:
The weight of an insert doesn't give enough of an effect for me unless I use a heavier stock material. I've stuck a rolled index card in the cap of a Lakubo mod, I could feel a difference then.
Insert Effect:
The most important aspect of inserts, for me in modding, would be that they make a clear-bodied mod much easier to watch when spinning. My eyes don't seem to work nearly as hard when spinning for long periods using a mod with an insert as they would if I was spinning a clear mod. The insert also makes the entire pen seem more "solid" to me and easier to spin in general. I assume that it's more a mental thing for me since I don't feel a weight difference. -

No points, just saying and giving others ideals.
Thanks for adding on Sketching.
I can easily feel the weight of the pen as a spin because I always transits to heaving > light > medium >heavy and so on.
Insert contrast could relate to the black & white situation. -

But the insert does not take away too much momentum. It gives a lot of aesthetic appeal for some pens with clear barrels, so i think inserts are good. A lot of say... RSVP's look much cooler with inserts then without.IMO. Plus inserts are also something to look at when your not spinning the pen. It makes it look just all-around cool.

Backgrounds should be kept to an inoffensive light-wood colour and it works all round
It sounds like a guide on colour selection for pen mods, inserts and backgrounds in order to get the best effect? Perhaps this belongs in a pen section rather than philosophy? -

Wow..
Now I really want to film a combo with a white barrel black caps pen against a shiny white background... can anyone imagine how awesome that would look?
All great ideas or.. what you should call it anyways ^^ -

I've made one insert and it was just a piece of cut up printed paper rolled up and stuffed into the barrel. How does it affect the pen in anyway other than the colours?

I guess it would add some weight in the middle of the pen, however small that weight is, wich would decrease it's so called momentum and well.. make it "harder" to spin :/
I doubt any normal person would notice this though.. -

When you were talking about momentum and then colors I thought you were about to say since dark colors absorb more light than bright/light colors then a comssa with black caps would have more momemtum than a comssa with white caps because the black caps would be absorbing the light making the caps heavier than the white caps.

Light absorption cannot add weight to a pen, light has no weight and therefore can only affect the look of the pen while its being spun and not the weight of the pen while being spun -

I was just saying that is what I thought Cybrax was about to say.
Though if you were to consider light as a particle and if the pen absorbed some of the light then it would gain weight.
And my hand is so sensitive to weight that I can feel the difference in the way my pen spins feels when an atom falls off my pen.

uhh a piece of paper in the middle hardly affects the weight distribution of the pen.
this thread sounds like its more about physics than philosophy... what is there to argue about when the physical laws are objective. -

actually, if you get the pen moving fast enough, faster than the speed of light, it would gain infinite mass.
since e=mc^2 ,
then m=c^2/e
get the e high enough, and voila! infinitely massive pen! wonder if that would change how it spins... haha
actually, i think that inserts are mostly only used on clear barrels. in your example, you compared a clear pen to a black and white bictory. obviously, the two are very different. one's clear.
now, i think that the pro and main reason for inserts are to add color, fluidity, and ease of sight. end of story

Once it reached the speed of light, all points in space and time would become one and the same. There would be no universe to spin in, or even a concept of spin. You would just have re-unified the universe! -

Pens spin much better with inserts in them IMO. (about RSVP mxes)
That is because momentum isn't completely dependent on weight at the sides. The weight in the middle of the pen can effect the momentum too, positively in some situations.
The middle of the pen shouldn't physically effect the momentum of the pen unless the insert in the middle would cause the middle to weigh heavier then the ends, which is very unlikely. Instead, it will simply add weight, (maybe change the balance, since the clear barrel in an RSVP tends not to be in the direct center of the pen) and aesthetic appeal.
Depending on what grip/cap you use, the effect of an insert can be more than just the visual appeal it adds. -

heck, who then would even care about ps? LOL
but back on topic. i vote inserts are almost necessary in order to make a clear barrel look good spinning -

Actually
e=mc^2
em=c^2
1/m=c^2/e
Just correcting some of the bad science in this thread... for your given equation increasing the energy decreases the mass.
@OP: Yes, adding mass to the center of the pen decreases its rotational momentum, but a piece of paper with ink on it is unnoticeable in your fingers. Anybody who says otherwise uses a stupid ass insert or is a liar. As for your theory of pen visibility or whatever, yes we know that bright colors stand out more than dark ones, and surprisingly, everybody also knows that they pop out more on black backgrounds. Now, if you want to spin something designed to look like a twirling baton, thats great & im sure you'll impress all the non-psers out there. However, those of us who want our combos to be seen by others will continue using visible pens on visible backgrounds so as to be easily viewed & critiqued by our peers... -

This thread still seems more like a thread about real-life pen mod issues. Thread moved to Pen Mods forum.

I think the insert is just to make the pen look kool!
Because i think most of the penspinners want a niche pen and not an ugly pen-like thing^^
And when the barrel is clear i don't see the spins so good because there's no color...
I think inserts doesnt take much momentum and realy look kool!
