Urgently looking for a React JS and Node JS developer. Please READ THE DESCRIPTION !!!

You need to write a program that will produce an image in which each color occurs exactly once with no repetition and no used colors. Colors are formed by combining a red, green, and blue component in the range 0..256. Your program will need to break each component into 32 steps -- 8, 16,24, .. 256 -- which means you will have 32,768 discrete colors. Your image will therefore need to be sized to accommodate exactly this number of unique colors -- for example, 256x128px (although other dimensions are possible).
