This is some code I designed to generate a random color or test another color (hex values) against itself or against another. It also keeps a list of liked colors and descriptions and displays them on the side. It will then, upon pressing the compile button, put the codes in an array-friendly format for easy transportation to the file. I've left some of the colors in the array for display purposes. It also requires an empty file called colors.html (with correct permissions) to function (for list-saving to work). - Kate, webmaster@griflet.com
