Use your setButtonColour function to change the colour of the button to, for example:
- Green
- Purple
- Yellow
--- hints ---
Changing the values of red, green, and blue that you pass to setButtonColour changes the colour of the button.
Colour values go from 0 to 255. Note that you are mixing colours of light, not colours of paint, so some of the results might not be what you expect!
Green is one of the three primary colours you're mixing. To create purple and yellow, mix two of the three primary colours in equal amounts. --- /hints ---
