Years ago I read on a "richrap" site I think he used water based clothing dye to color his filament, and then print with it, I would guess that the same thing could be done with raw plastic beads, Translucent filament would probably be feasible.

Did they indicate about what price it would be?  Also, do you know about how much longer until you have the other colorants in?

The price will depend on how much is needed for those materials which I'm waiting to hear back on.

The other colors came in but the grey doesn't seem to look grey.  I hope to be able to get the other colors on the website tomorrow. (Gotta take pictures, etc.)

Hmm, wonder how that would vary with copper powder (not the colorant, the actual metal) or wood dust - I would think it's a volume thing and not a weight thing entirely right?  Since 1lb of copper powder would be a lot less actual material than 1lb of colorant powder.

I talked with my plastic people and they said that I can get an additive that would work with wood dust and copper.  They are going to let me know about how much needs to be used for each.  As soon as I find that out I can get some additive in that will work with those.  Let me know if you would like to order some.

Ebay had a $15 off $75 order recently and I have nearly 30 pounds of plastic (might have gotten too much) coming.  ABS, HIPS, and PP pellets (I know the colorant won't work with PP).

Ok, I'll watch for it to become available.  Have you tried mixing any kind of GiTD additives in powder form?  Powder form results in easier color consistency than colorant pellets without the need for a pelletizer right?

As soon as I can see that people want powders, I hope to be able to get some Glow Colors. 

Powders do get more of a consistent color from my experience.  I haven't done any BIG batches, only .5 lb to 1lb batches, but they turn out nice and consistent.  The big filament makers use powders to make filament.

You have the Red, Yellow, Blue, White, and Green Dry package for $13.50, or about $2.70 a pack, could you do a bundle with all that plus the new orange, brown, black, and grey for the same $2.70 a pack or 9*2.70, $24.30?  Shipping adds on about $8 so getting as much colorant in one package as I can only makes sense.

I will be creating a bundle for all of the colors, tho it will be a bit more than $2.7 each since the Grey is almost twice as expensive as the others and the Orange is 20% more expensive than the other colors.  Once I get the bill for shipping then I'll better know what I can do a bundle for.

Does it come with the additive in it already from the manufacturer, or do you add it?  Could you sell the additive separately?  I'm trying different types of plastic now, but once I have enough wood powder saved up that will go through a 250 micron mesh I plan to try that and would be curious if the additive would help wood powder stick to the pellets the same way it helps the pigment powders to stick to pellets.

It comes to me pre-mixed.  If you would like I can check with them next week to see if they can send some to me.  The difficult part with mixing it is that you have to mix 1-3% by weight.  The smallest amount I can get from them is 1lb.  They tell me that unless you are mixing at least 1lb at a time, it doesn't mix well.  1lb of powdered pigment is usually good for 300-400 lbs of raw pellets. Which is why we sell 10g packets that is good for about 4.5lbs of pellets.

Pigments are generally formulated for a particular type or type of plastics.  The powdered pigment that we have is formulated for use with PLA, ABS, HIPS, PC, and Nylon. 

The pigment that we currently have is not compatible with PP or PE although we could get some that is formulated to work with them. 

We have some additives mixed in with the pigment that help it to adhere to the pellets.  Initially we didn't have that and it was a complete mess with pigment ALL over.

We currently have Red, Yellow, Blue, Green and White.  We expect to have by next week Orange, Brown, Black, and Slate Grey.

Many years ago I worked next to the pigment department in a plastics factory. They formulated the mix to be added to the natural colored pellets. Titanium dioxide is the standard white pigment and adds opacity and zinc stearate was used as a lubricant to help the plastic flow better and aid in the release from the mold.
