Color Choice

After reading I have come to my own conclusion that color can have a purpose but can be aesthetically chosen by the designer.  In my first draft I used color to represent the different weeks and chose specific color based on colors of music albums.  Now for the second draft I am doing the same thing.  The color choice of blues and yellows is random but the purpose is not. The blues represent the weeks and the different hue shows the change from weekday to weekend. The yellow represents when projects are due.  I could have chosen the opposite color to blue but it was not aesthetically pleasing. So I as a designer made a personal choice to use yellow.
