Color Color Everywhere
The topic of the day was color. Since we picked up that first crayon, color has been a part of our lives.
"What s your favorite color?"
"What color is your house?"
"What color is your car?"
"What color hair do you have?"
"What color are your eyes?"
We take it for granted, until today.
The class began the same as any other with attendance, review, questions and intro. Then it got interesting. The class started with a discussion about color and how our eyes see it (Additive Synthesis for those interested) and how they learned about primary and secondary colors in art class. The students discussed how all colors come from the primary colors and that how you can mix them and get all the other colors in the crayon box.
Then things got interesting. I asked how is it possible for a computer to replicate those colors on a monitor. How is it possible to take a digital picture, move it to the computer and e-mail it to friends and or family and allow them to see the same thing. Additive synthesis, that is how. The combination of red, green and blue, that is how. After discussing how color is defined in computer language as a hexidecimal number and how there are websafe colors and hue and saturation and brightness, I though their heads would explode. Just for fun I thought I would throw in some binary addition.
Tomorrow I think there will be lots and lots of review.
