RGB reaction plots

Colour can be considered in proportions of red, green and blue light. By analysing the r,g,b values of colour, chemical reactions can be followed and a 2D plot produced to show the reaction occurring. View other images in the RGB gallery

This shows hydrochloric acid with red cabbage indicator. Slowly sodium hydroxide is added, the RGB values are recorded as the reaction proceeds. The values are converted into a 2D plot using python script.
