Optics B/C

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.

So will the tests follow previous art standards, or the modern color theory? I remember back in elementary school art class where we learned that red yellow and blue were the primary colors.

Go with the more modern theory. This is Science Olympiad, after all.

Saying this is Science Olympiad gives no explanation as to why we should use the modern theory...

Can you name the source of your information?

No, I think you may be going with the artistic primary colors. It should be green, red, and blue.

You should use the modern theory because scientifically the optimal primary colors of pigment are cyan, magenta, and yellow.
http://en.wikipedia.org/wiki/Subtractive_color
http://en.wikipedia.org/wiki/RYB_color_model "It predates much of modern scientific color theory, which has demonstrated that magenta, yellow, and cyan is the optimal set of three colors to use when mixing pigment."

Most references you find that say red, blue, and yellow are the primary colors of pigment are referring to art, not science.

Primary colors of light: Red, blue, and green
Primary colors of pigment: Magenta, cyan, and yellow

[Schrodingerscat]

The three pigments in the human eye absorb red, green, and blue, hence their role as primary colors in the human perception of light. Cyan, magenta, and yellow are the colors percieved when one of those colors is removed while the other two remain. They also serve as the primary colors of pigments because they are substances that remove specific colors of light. Unless a question appears to specifically refer to the old RYB color model, use the RGB/CMYK model in your answer because it is directly related to light and the physiology of color perception.

Well, I stand corrected. Thanks for the info. I would have taught others the wrong thing if this hadn't turned up...

That...would have been bad. Cause I wouldn't have corrected you either.

Since I am new to this event this year, can I get a general idea of how much information to put in a binder? I know that loading it with stuff will make it hard to find. I am thinking about putting like a Wikipedia page in there for each part of the eye, and creating a table of contents, to make finding the information easier. I have separated the optics things into a few sections, such as a page just for the equations and principles, along with a page just showing the lenses and mirror diagrams.

Do whatever works the best for you.Put in there whatever things you aren't sure about. It's good to include a sheet of equations with all the equations you need to know, and then just put in some stuff that you think you're going to forget or something. Table of contents woks, but you should probably also tab everything. A little easier than just straight table of contents.
