There is now no more excuse of being a color blind person if the Touch Color concept ever takes off – this device is but a combination of a thermal digital tablet and a rainbow colored picking ring, allowing even a blind person to paint colorful pictures on the tablet itself. There are 24 colors on the ring which can be differentiated through the use of Braille dots, while the varied temperature is generated by the embedded LED bulbs. We suppose this would work well with those who have lost their sight in later years of their lives, retaining an image of what colors look like mentally.
