Thanks for the use of the picture here Arkansas.
CC1, to your original question....the so called pearl hi lites sold at Do-It are hi lites, not pearl. Here is the link to their pearl powder....

Unlike hi lite, pearl powder is white and will take on the plastic color you put it in. Pearl powder, because its base color is white, will opaque a transparent color if you add a lot of it. Used in any color the pearl will tend to lighten the color. Pearl is super strong and a very little will create the pearl swirl in a transparent bait, but since it works INSIDE the plastic it will also start stopping light with the addition of very little powder.
If you add enough hi lite color to clear plastic you will indeed not end up with clear plastic but one colored to some degree in the color which the hi lite is labeled. Add enough of the hi lite and you'll cloud the clear plastic just like a pearl will do only in color. If you add a hi lite to a colored plastic in proportions to get the surface sheen you probably won't see much color change unless the plastic color or hi lite color is a serious contrast color. Lots of blue hi lite in a transparent purple plastic, like the picture shows, will indeed create the illusion that pearl has been used and the color of the plastic will shift as well. The purple plastic in this picture I also saw PRIOR to the addition of so much more blue hi lite and it was definitely purple transparent with a slight blue sheen on the surface.
One has to be careful in buying products sold as pearls in the automotive paint arena. Many of these pearls are colored. Very few pearl powders sold for plastic specific use are colored. White is the usual and silver is yet another color of pearl for plastic use. The two products are not interchangeable....pearl
s won't give you the same effects in plastic as hi lite will. But the picture speaks for itself in that adding a ton of hi lite can create that pearl effect in a plastic. This is all stuff you can toy with and see first hand how too much hi lite will work in your plastic be it clear or colored.
Apparently Bob and I are feuding over something completely different. I have no idea.
