Hearing Colors

We wanted to explore how blind people could understand what colours there are in their surroundings. We created a “colour scanner”, which using a camera, analyses a live image for colours by measuring the amount of red, green and blue in the image. Using these values, each ranging from 0 to 255, we are playing three different tones in a sequence. To make it easier for the ear to separate the sound of the colours, we set individual waveforms for each using the Music & Motors module for Arduino.
