1. Introduction

In the sweets and candies, there are always colour dyes that make it look colourful and stunning, But have you ever wondered what actually makes these dyes? For our project, we decided to compare the common dyes present in different colours used to make the dyes of these artificial candies.

Research Questions 

Are the dyes used for skittles the same as food colouring dyes?


The hypothesis is that the Rf value of the common dyes and food colouring of skittles will be the same.
