This small tutorial should show you how to have transparent looking glass and plastic without using ANY alpha or layers. Another math tastic tut from me. I wanted to provide people who use MS paint a way to get transparent looking glass and such. No layers no transparency ANYWHERE. All solid colors with no transparent channel.
 
 
I'll show you how to fill this pool with water and NOT use alpha transparency layers.

It mimics the effect of some transparency but programs may do it differently. There are many ways to do this. I can think of about 2 different processes. So no, I can't say that all transparent layers use this calculation. I do guarantee a perfect result however.
 
DO note that some colors blend to pure gray. This is correct because light colors do not behave like pigment colors.
 
for example
 
Pure blue + Pure Yellow= Gray
 
Blue 0, 0, 255 + Yellow 255, 255, 0 will turn gray at 50 percent transparency. This color seems to be incorrect, but it is correct.
 
If you want to see this bizarre fact try the experiment in a program that handles alpha. If the programmer did their job correctly, you will get gray.

yeah, I was reading about the color theory the other day and noticed the diference between additive and sustractive colors.
