 If you've ever had to spend a long time perfecting the colour scheme of a plot, you'd find the Plot Colour Helper handy. It's an RStudio addin that lets you interactively choose colours for your plot while updating your plot in real-time, so you can see the colour changes immediately.

If you use the `allowTransparent = TRUE` parameter, the input will display an additional slider that lets you choose a transparency (alpha) value. Using this slider allows you to select semi-transparent colours, or even the fully transparent colour, which is sometimes useful.
 
 When using transparent colours, the return value will be an 8-digit HEX code instead of 6 digits (the last 2 digits are the transparency value). For example, if you select a 50% transparent red, the return value would be `#FF000080`. Most R plotting functions can accept colours in this format.
