1. Light and color

2. When light strikes an object
When light strikes an object it can do one of three things.
transmitted
Light passes through object
reflected
Light bounces off object
absorbed
Light does not pass through or reflect

3. Reflected
Absorbed
Transmitted

4. Why you shouldn’t wear black t-shirts in the summer!

5. Transparent, Translucent, & Opaque
Transparent – light passes through; clear
Translucent – scatters light as it passes through, details are blurred
Opaque – reflects or absorbs ALL of the light; cannot see through it

6. Transparent vs. Translucent

7. The Color of Objects
The color of an object depends on the material of the object and the color of light striking it.
OPAQUE OBJECTS: they are the color of the light they REFLECT.
TRANSPARENT & TRANSLUCENT OBJECTS: they are the color of light they TRANSMIT.

8. OPAQUE OBJECTS – REFLECT!!
Bananas are yellow
because
they REFLECT
yellow light!
Leaves are green
because the
chlorophyll in leaves
reflect green light and
absorb the other colors.

9. TRANSPARENT & TRANSLUCENT - TRANSMIT
Filter appears green because it TRANSMITS only green light.

11. What color does it appear to be?

12. Colored glass transmit they color they appear!

13. The colors of objects can change under different color lights.

14. Mixing Colors of LIGHT The primary colors of light are:
RED, GREEN, and BLUE.
When they are mixed in equal amounts they combine to make WHITE light.

15. Mixing Colors of PIGMENTS
Inks, dyes and paints contain PIGMENTS.
The primary colors of pigments are:
MAGENTA, YELLOW and CYAN
When pigments are added together, Fewer colors of light are reflected (more are absorbed). For this reason, it is called SUBTRACTIVE.

16. Notice they mix to make BLACK!
Black absorbs all
colors of light!

17. LIGHT vs. PIGMENTS

18. Adios!
