Make color picker work in drawingboard.js

Job ID: 31272178

Budget: $30 – $250 USD

I've got a page where you can make a drawing: https://www.dictionary.university/i/draw/index.html
( download html: https://www.dictionary.university/i/draw/draw.zip )
( I'm using https://github.com/Leimi/drawingboard.js )

It comes default with a color picker tool that works perfectly! You can see it in action at the bottom.

At the bottom of the page you see 3 buttons I added myself: Red, Green, Blue.
I want that if you click the red button, that the color changes to red, blue to blue, green to green.

I'm not sure how to do it. Maybe for someone with better javascript/jquery knowledge can have a try?
