Useful when you need a small tonal family rather than a whole new palette.
Useful to know
Four things worth knowing.
Where it stops.
It solves the named job, not every problem around it.
What to inspect.
Use the number as a signal, then look at the real text size, weight, background and surrounding colours.
Worth knowing.
Keep the original until the finished result has worked in the place you made it for.
