Before the computer, designs like those below would have been very time consuming to create with traditional painting mediums. Doing simple designs can be fun and a good way to familiarize yourself with a program like Photoshop Elements 2.0, which is what I used here.
You can easily create a black and white design on the computer by using the Line Tool and the Rectangular Marquee Tool. For this experiment, just about any simple design will suffice.
I add colors with the Paint Bucket Tool, if I don't like the result I can easily change the color. On the second version I create a white design by reversing the original. This is done by pressing Control and the letter i at the same time.
Another unique black and white design, these are fun to create, just let yourself go wild.
This is a very complex design that takes a bit longer to do, when you add color it's even more interesting. As a final touch I added the white rectangle in the center.
A fairly complex but pleasing design.
With the addition of color the whole design takes on a new character. Studies like these will help to develop your design and color skills. The image on the right is a negative of the first image.
