The one thing that we have to constantly consider throughout every class, assignment and computer program. Are they global? CMYK? Did it work on your home page? Can you see the text over it? Can you find it with the eye dropper thingie? And finally did it print the way you see it on screen (likely never with my luck). On the bright side it’s consistent throughout every application we use and it’s also pretty fun to play around with in my sketchbook.
