How do you obtain the color yellow from the primary colors: red, green, and blue?

Question

On any video display, there are three primary colors used: red, green, and blue. How do you obtain the yellow? From what I was taught, the 3 primary colors were red, blue, and yellow. In which case, red+blue=violet, red+yellow=orange, yellow+blue=green. If red and green are mixed they make a dark, almost black color because they are complementary to each other. This occurs also when blue+orange=dark color and violet+yellow=dark color. So how is yellow made from just using red, green, and blue?

Answer 1

The colors are not representative of the true primary colors, which are red, blue and yellow.  The RGB color model is an additive color model in which red, green, and blue light are added together in various ways to reproduce a broad array of colors. The name of the model comes from the initials of the three additive primary colors, red, green, and blue.  So in short, two different media, you don't make yellow.

Answer 2

There's a big difference between mixing colors that are PIGMENTS and mixing colors that are LIGHT.

PIGMENTS do exactly what you're describing; they're "subtractive." when you mix the entire visual spectrum of pigments together you end up with black. The three primary colors are Magenta, Cyan, and Yellow, names you probably recognize from your color printer cartriges.

LIGHT isn't so simple. You make black with light by... not having ANY light. mixing every color in the spectrum of light will create white, as opposed to black. The three primary colors are Green, Red, and Blue.

Answer 3

Green is not a primary color. Yellow is.

Answer 5

Like everyone says, red, green, and blue are not primary colors. It is the color model used for things like tv, computers monitors, and the like. You don't use this for paint and other mediums

The scale of values is from 0 to 255. You can get a bright yellow with Red set to 255, green set to 234, and blue set to 0. If you set Red, Green, Blue to 0, you get black. If you set them all to 255, you get white.

This is useful when you're making colors for graphics to be used on a website using a program like Photoshop. This isn't useful if you're mixing paints.
