You wont see me making too many clear colored figures. The reason being, and there are several start here.
Wherever there is a hole in the body, this allows light farther into the figure. So the body shade will vary unless the pins going into those holes are the exact same shade.
You don't get the same shade for all the parts in one pour. The smaller parts will be a lighter shade. The larger parts will be a darker shade.
Painting is a problem. If you paint black anywhere or darker colors, it darkens the shade around it. sometimes changing the shade.
The same with combining clear colored parts. The colors change. A clear red over a clear blue will have the red looking purple.
So you have to really watch it with the clear colors. What starts out as a good idea gives way to a lot more work and in some cases might not look as good as originally thought. And then the extra left over parts. And then if you get the shade wrong, which is the easiest thing to do, you end up chasing a color and making a whole pile of different shaded parts. Which can happen with solid colors just as easily. Tinting is an art form unto itself.
This is just my opinion, but I think that's why solid white is used more often than not for clear colored figure accents. Its the color least likely to change the shade or have the least effect on the shade of the clear colored parts.
