The art generator I used for this piece of art was called "Viscosity." I liked this one because you could pick the colors you wanted in the art instead of default colors, the brush was fun to play with, and after you used the brush you could move the points individually to create an even more creative final product.
This generator was called Graffiti Art. I like this site a lot because you can not only choose the color of everything in the image, but also the design, text, width, height, and rotation of the text. This website was very fun to just play on and explore.
This web art generator is on www.coloring.com. On this website, you are able to pick any design that catches your attention and color it. What I like about this coloring website is after you select a color, you just tap the space you want it to be in, instead of trying to color inside of the lines.
