So division B doesn't need to no polarization. I created notes and studied it.

Always good to overprepare, dearest.

So what textbooks are you guys using.
For the physics components of this event, I'm finding everything in the GIancoli textbook.
Is there a good biology textbook for the parts of the eye, and another book for the things we need to know about colors? Or are most materials online?

For parts of the eye, get the textbook of someone who's doing Anatomy on your team. That usually has all you need to know about eyes in it. For the eye sensing colors and stuff, just know the difference between trichromatic and dichromatic, rods and cones and what they sense, and the difference between additive and subtractive colors. If you know that, you'll be okay.

You know, a lot of this stuff for optics is stuff that you can google. You can easily get the parts of the eye and some stuff about colors by searching eye and colors on google.

I don't think they are limited on what they can test you on, and I don't believe that the anatomy textbook contains enough information on each individual part of the eye so I'm looking through some websites online.

For the colors section, I'm finding a lot of different answers for things like what are the primary colors? The wiki sections says to follow the Red Blue Green model, but some websites say Red Yellow and Blue.

Additive colors are red/green/blue. Subtractive colors are red/yellow/blue. Know the difference between the two.

That is incorrect. The primary colors of light are red, blue, and green, and the primary colors of pigment are magenta, cyan, and yellow.

Additive mixing of colors refers to mixing colors of light (equal amounts produce the secondary colors of light of magenta, cyan and yellow), subtractive refers to mixing of pigments (equal amounts produce red, blue, and green). They're called this because in additive mixing you add wavelengths of light, and in subtractive you subtract wavelengths of light.

Red, blue, and yellow, despite what your kindergarten teacher may say, do not make up the primary colors of anything you'll use in Optics.

Actually, the primary colors of pigment are red, blue, and yellow. Magenta, cyan, and yellow are the secondary colors light.
The primary colors of light are blue, red, and green, as you said. They are also called addative colors. Blue light plus red light equals magenta light. Blue light plus green light equals cyan light, so magenta, cyan, and yellow are the secondary colors of light. Red light plus green light equals yellow light.
Red, blue, and yellow are the subtractive colors.

Red, blue, and yellow were previously the standard for subtractive colors and are sometimes still used when teaching art, however, modern scientific color theory has proven magenta, cyan, and yellow to be the optimal set for pigments.
