PCC - Color (Lesson)

Color

Red, blue and green are the primary colors. From these all the other colors may be made by using a mixture of intensities of each of these. You can see the mix to the left, even giving the white color in the middle.  

So how is color mixed? Color is given intensities from 0 - 255, 256 instances of the color intensity. RGB, or red, green, and blue make up the colors so for short the RGB is the reference to the mix of these colors yielding another color.  

Black is the absence of all color, what is seen when there is no light.  

White is the complete color spectrum, the light. White reflects all light. Without light, the color seen is black.

Now look at color mix in Alice.
