I have an issue with an app i am trying to build.
There are 5 states, which are referred to as Intensity 0 all the way through to Intensity 4.
Each Intensity has a specific colour fill.
Intensity 0 - white
Intensity 1 - Blue
Intensity 2 - Green
Intensity 3 - Yellow
Intensity 4 - Red
The basic premise is that you select one of these Intensities (0~4) and then drop whatever Intensity you have selected on a 15x36 grid, thus creating a pattern.
So, one click on the intensity to select it and then click away on the grid to drop the selected intensity to create a pattern
