New palette when only using two colours #4

Closed lee-bunce closed 1 year ago

lee-bunce commented 1 year ago

The main palette in the colours guidance is [Dark Blue, Turquoise, Dark Pink, Orange, Dark Grey, Light Purple], in that order.

When only using two colours however, it recommends [Dark Blue, Orange].

Add scale_colour_discrete2 and scale_colour_fill2 functions to implement this?

Rather than add new functions for use of two colours, I've added a palette called main2 that just includes dark blue and orange. If a chart requiring two colours uses a different main.. palette, then a warning is generated to direct them to use main2. We can make sure to include something about this in the documentation too. Does that seem ok?

Sounds good!
