The chief aim of color should be to serve expression as well as possible. Henri Matisse

Admin

• Dr. Davis and I discussed the exam and decided that we'd prefer to distribute it after HW3 comes in. So you'll get it tomorrow.
• My email aplication has been acting up. If you want a meeting with me and haven't scheduled one, please see me after class and we'll pick a time.
• Reading for Wednesday: Raster Graphics and RGB Colors
• SACNAS Ice Cream Social Thursday, September 19th at 8:00PM in the Biology Commons
• EC Opportunities:
  • Convocation this Wednesday
  • CS Extras Thursday @ 4:30: Kim Spasaro on Linguistics Programming
  • CS Table Friday (Pair programming)
  • Other?
• I also encourage you to attend any of the other Title IX talks/events.

Pair Programming

• Idea: Instead of one person, you have two
• Two roles: Driver and navigator. (A bit more complex with three people often two navigators.)
  • Driver - write code
  • Navigator - guide
  • Need to rotate roles.
• Why do we do it? What are the benefits?
  • "Two minds are better than one"
    • Helps avoid wrong directions
    • Ideas build upon each other!
    • If your navigator has access to the reference material, the driver is more efficent - doesn't need to switch windows, etc.
  • Having to explain what you do helps you
    • understand it better
    • make fewer careless mistakes
  • Some of you folks are already too reluctant to ask for help
    • Encourages you to ask and be unsure
  • "Fresh Eyes" - It's hard to see problems in what you've done
  • Over the long term, you'll hvae to work with other people on projects, so get used to it
• Evidence from both industry and classroom suggest success
• How should you behave as part of a pair?
  • Know your role - Navigators should guide, not just steal the keyboard
  • Communicate
  • Be patient
  • Switch roles
  • Don't be afraid to ask for help
  • Don't be too assertive
  • Don't be too passive - you won't learn if you just watch
  • Postive criticism
  • Explain

Clicker Questions

• Gender issues and pairing
• Gimp Tools

A bit about design

• Goal "Oooh pretty"
• But perhaps we should also understand millenia of experience on design
• Many principles
  • Symmetry
  • Balance
  • Depth
  • Color
• Goals in image making
  • Guide the viewer's eye through the image
  • Keep the viewer's interest (Kluber says that simple representational art will not keep the viewer's interest)

A bit about color theory

• Three ways to think about colors
  • Making it with light - Red, Green, and Blue More light - Brighter
  • Making it with paint (subtractive) - Red, Yellow, and Blue More paint - Darker
  • Alternate approach to paint
    • Hue - Basic color
    • Saturation - How much of the pigment you mix into the paint
    • Value - Brightness
• How do you as a designer use colors?
  • Complementary - Tends to make colors "pop" or vibrate
  • Analagous - Three neighboring colors on the color wheel
  • Monochromatic - Variants of one color
• Other uses
  • Feeling: Warm/cold
  • Depth
