Color has you test the accuracy of your perception of color as you learn about key concepts in the theory of color and design. Simply move your cursor about the large color wheel and click when you have matched the color of the timer inside, before time runs out. Later levels have you matching multiple colors at once, giving you the opportunity to learn about complementary, analogous, ternary, and quaternary colors, all in the context of the game.
It's always intriguing when a game developer takes a technical, even mundane, activity and makes it into a competition. KernType, a unique puzzle game developed by Mark MacKay for edutainment site Method of Action, charges you with dragging the middle letters of a given word for a given font to make it aesthetically perfect. Your result will be compared against a professional typographer's, and you will be given a score based on how close you get to their solution. It's not a concept that survives multiple play-throughs, but it's quirky fun.
