用最快的速度在色譜上找到指定的顏色，考驗你的反應和對顏色的熟悉度！

You should barely be able to see a difference between the inner and outer color. If you're on a laptop also make sure to adjust the viewing angle of your screen. Don't worry if you can't see all the colors, the game has built-in tolerance and will give your a perfect score if the colors are very similar.
