In the beginning, the user was only able to select RGB (red, green, blue) through a slider since it was the colour scheme that was the most widely used. During the sharing session, we were asked “Why RGB only?” and that prompted us to give the user more options.  

Users are now able to select four kinds of colour schemes: RGB, CMYK, and HSL as well as input the HEX code directly. The professors also shared another concern: the sliders were not accurate enough since the specific values of RGB were not displayed, and due to clumsiness, the user may not be able to select precise values to dispense the same colour consistently.  

Hence, we have decided to display the values selected, and have a rotary knob to increase/decrease the value by a small margin. This improves the quality of the UI drastically, so thank you to the professors, and good luck to our coders.
