Use the Red, Green & Blue sliders & 'nudge' buttons to change the color of the outer ring to match the color of the inner circle. Ultimately your goal is to create a palette of fourteen colors each with a 100% color match. Each color is randomly generated and an exact match is always possible. Every palette will be different. When you think you have a perfect match tap the ‘Confirm & Reveal’ button. The color and score will be added to the palette. After reviewing your score tap ’Next Color’ to continue. There is no time limit so relax and meditate on the colors. How many times can you complete a perfect palette ?
