Subtractive Theory of Color

Opaque Objects:
When white light shines on an opaque object such as a red apple all the colors except red will be absorbed into the object except red. The color red will hit the object and reflect off of it to appear red.

Transparent Objects:
When white light hits a transparent object like a blue waterbottle all the colors except for blue will be absorbed. the blue color will reflect as well as travel through the object.

Compound Filters:

This shows when white light hits a yellow compound filter the colors yellow, orange and green will be transmitted through while the rest are absorbed. Then they continue to hit a blue compound filter which only allows the green color to pass through, so your results are the color green.]

*If an object is black that means all the colors from the white light are being absorbed into the object.
*If an object is white this means that no colors are being absorbed they are all being reflected off the object.

We also looked at adding colors together to see what it would produce.
