2White Light White light is a mixture of all colors of visible light. Black is the absence of light.This font is black because no light is shining here.The light shines all around it making white.
3Mixing colors By mixing different colors you can create new colors. The goal for a printer make as many colors possible out a few starting colors.Out of 3 colors we can make all colors.
4Color by subtractionPigments (dye, ink) absorb certain frequencies of light and reflect others.Yellow pigment reflects yellow light and absorbs other colors.When you add another pigment it subtracts a color by absorbing it.If you mix all colors perfectly you should get black.
5Subtractive primary colors You can make almost any color out of different concentrations of Yellow, Cyan, and Magenta pigment.Art has long used Yellow, blue, and red.Both of these sets are shades of the other.You can make yellow, cyan and magenta from yellow, blue and red.You would just use more of one color and less of another.
6Where you will see the subtractive primary colors Every color printer has 3 cartridges (some also have a 4th black cartridge)Those colors are cyan, magenta and yellow.The 4th cartridge isn’t really necessary, however it was quickly found that 99% of printing is in black, and replacing one cartridge is cheaper than replacing 3.

10Filters A filter is something like colored glass or plastic. Color filters allow certain colors to pass through and absorb others.They work the same way pigments do, except pigments reflect color, where filters transmit color.
11The hidden message trick These are made of several dots and linesThe ones thatreflect redWhen you put a red filter on top of it, all that reflect red will appear red, cyan will appear black, because it absorbs the red light.And cyanwhich absorbs red
