Color Highlights Unit 6

Isaac Newton White light is all light combined. Newton shined light through a prism into separate colors. He then separated just blue light through a spectrum and it was just blue on the other side…blue is not a combination of other colors! **This will be considered a primary color.

Rainbows As white light passes through a prism, shorter wavelengths refract more than longer wavelengths, and colors separate. Red light moves slowest so it bends least. Violet light moves fastest so it bends most.

Primary Colors Red Green Blue When red light strikes a surface, red light is reflected. When blue light strikes a surface, blue light is reflected. When red and blue light strike a surface, they bounce back and combine to make magenta.

Secondary Color Cyan Yellow Magenta These are each a combination of 2 primary colors. One primary color + a primary color = white light. (complementary colors)

Pigments Pigment a material that absorbs some colors of light and reflects other colors. Primary pigment colors are Cyan Yellow Magenta

Pigments Secondary colors of pigments are: Red Green Blue Complementary colors of pigments 2 pigments combined to make black
