When we were young and were learning how to use the computer in our computer subject, we waste our time in Paint. Since games such as the Purble Place and Solitaire are removed from the desktop, we have nothing to do whenever we're done with the task given to us by our teacher. We draw a lot of lines in Paint and fill the closed figure with many colors. It's always a disaster but we loved it.
"Sangfroid" means calm or cool. I believe that I can be composed whenever I look at this image. I used only 6 colors. I learned from my art teacher in high school, Ma'am Eva, that 4 colors are sometimes enough to make an image lively.
