Hello, I am having trouble with the $global-color-pick-contrast-tolerance.
Basically i really don't know how to call it in - I always seem to have trouble with the sass functions and mixins - i understand how they work but not really how to use them.
So I have a nave bar and I wang the links to change from black to white depending on what colour is behind them.
Attached are my failed attempts. Any help would be great.
