I change foreground and background colours on every project track's clip(s), so I hit this bug as soon as I'd updated to Lexington.
I always use standard colours in every project so I can instantly identify each track:
- Drums and percussion: red background, white foreground
- Bass: brown, yellow
- Keys: royal blue, white
- Strings: light green, purple

Good tip. What's the "more"? 

Thanks Craig, my other standard colours I always use:
- Synths: Purple background, yellow foreground
- Brass: yellow, dark blue 
- Guitars, rhythm: light pinks, dark purple
- Guitars, lead: bright pinks, dark purple
- Vocals: grey, purple
 
These are the colours that these instruments suggest to me!
