Potd12 Color Potd12 Color Presentation Transcript

  • Painting of the Day #12
    • Looking at Paintings #2- Color
    • Aka: The most annoying Power Point presentation ever!
  • Color Theory
    • When Isaac Newton was only 22, he began a study of color that resulted in the first color wheel. The first color wheel was one of additive color. There are 2 kinds of color wheels—additive and subtractive.
    Subtractive Color mixing is the mixture of pigments – like mixing paints. The primary colors in the subtractive color wheel are red, blue and yellow. The theory states that you can mix any color with these three colors (the theory is wrong-try mixing flourescent yellow!). Additive color mixing is the mixing of light. Primary colors are Red, Green and Blue. When you mix these together- you’re supposed to get white. In additive color, the mixture of all light waves=white. That’s why it’s called additive, the more colors that are added the lighter the mixture becomes. In the subtractive color wheel, the mixture of all the colors will give you a neutral grey.
    • This is the best color wheel ever. WTG Ali!!
    • Complementary colors can be found on opposite sides of the color wheel. Red’s complement is green, oranges compliment is blue and yellows is violet.
    • The name is a bit misleading. When you mix two complimentary colors, they hardly compliment each other, they make a neutral brown color. When you put them next to each other though, they emphasize each others properties. Look at Monet’s Impression Sunrise...He puts a sun with about the same value (value is dark vs light...think of a progressive white to black scale and that is usually how you can measure how dark or light a color is) as the sky. The blue in the sky emphasizes the illumination of the orange and makes it look much more intense and sun-like.
  • Primary and Secondary The primary colors are red, blue and yellow. Secondary colors are violet, orange and green. The old theory states that you can mix any colors with the 3 primary colors. Unfortunately, once you mix two colors together, the resulting color has less intensity as either of the initial colors. So the more you mix, the muddier and more neutral things get. The secondary colors make nice harmonies, they’re less intense than the primaries.
  • Why you see color Let’s say you’re looking at something…let’s make it a dead alien. Being that it has recently passed on, it still has it’s lovely green hue (hue=the true color, unaffected by shadows or intense light). Note how the red (green’s complementary color) frequency is the only color that gets absorbed into the alien. All the other colors reflect off the skin, thus giving the alien his creepy green hue. That’s how it works, kids. If all light waves bounce off an object, then your object is white. The additive color wheel illustrates this. The addition of every light wave substantially lightens the mix. If all of the light waves are absorbed, then the object is black. Think about it, if no light is reflected at the viewer you wont see anything but an absence of light.
  • Red
    • I love red! It’s really an interesting color. The rods in our eyes don’t perceive red very well, so once darkness rolls around, red is the first color that you have trouble seeing.
    • Personally, i believe that this stems way back from when we were fish people. Ya see...when light penetrates water, the red light waves can only penetrate up to about 12 feet. After that...no red at all (so don’t fish with red fishing lures if you’re going deep). Ever see the military flashlights with red lenses? They use the red lenses b/c the red doesn’t effect your rods very much and therefore doesn’t kill your magenta (night) vision. Using white light destroys your magenta vision and takes about 30 minutes to get back to full. Also, when deep sea submarines want to see what they’re looking at without freaking out the fish, they use an intense red light. The fishes eyes don’t pick up red light at all. Connection? Hmmmmmmmm.
    • I can’t find the awesome table of the penetration of light waves in water that I have in a book at home. As an aside though, don’t do an image search for the keywords “color penetration in water” when you’re at work. Yikes!
    • Red invokes emotions of violence, passion, guilt and sin. Sign me up!
    RED!!!! I love red! It’s really an interesting color.

Do you hate looking at this yet? Do you Believe me that red is the most intense color yet? I can’t find the awesome table of the penetration of light waves in water that I have in a book at home.

  • Blue.
    • Blue.
    • The color wheel is split in two by what is referred to as warm and cool colors. Blue is the coolest along with green and red and orange are the warm colors. Violet and yellow are considered to be warm or cool by their tone (a yellow that has more green in it would be considered cool and a yellow with more orange in it would be considered a warm color).
    • Blue has the ....wavelength and penetrates deepest in water. The deeper you get into water the more exclusive blue is. When you get so far down that you can no longer see the blue wavelengths, all you’ll see is black. Unless you can see ultraviolet. Which you can’t.
    • Blue is considered to be a sad emotion (He’s got the blues). Contrary to popular belief, the term “Blues” referring to the musical movement doesn’t have to do with sadness, but the extensive use of “Blue notes”
    • In jazz and blues , blue notes are notes sung or played at a slightly lower pitch than those of the major scale for expressive purposes. Typically the alteration is a semitone or less, but this varies among performers. Country blues , in particular, features wide variations from the tonic but still with the blue-note feeling. Blue notes are often seen as akin to relative pitches found in traditional African work songs .
            • That’s from Wikipedia.org
  • Primary Colors- Yellow
    • Yellow is a color that’s related w/ a lot of bad stuff- cowardice, disease, Asians (I’m half Asian if you didn’t know :P)... The oldest record of the word ‘yellow’ was in the book Beowulf- to describe a shield from a yew tree.
    • ...there’s not really much to say about yellow. It’s a nice color. It’s not too intrusive and is the lightest (value wise) of the primary colors. Old west prospectors used to use yellow to describe gold and in the South, some people use the word yellow instead of saying, ”Egg Yolk”.
