A simple helper I wrote so I could reference the same colours throughout my app more easily.
I have a color pallette for my app with named colours which I can refer to whenever I need to set the colour for something.
getmethod returns a 3-value tuple containing the Red, Green and Blue values as decimals.
getOvermethod returns a 4-value tuple containing the Red, Green, Blue and Alpha values as decimals. I've chosen a 75% transparency for all my colours which works well for my project.
Feel free to copy and modify this as needed.
