Not enough contrast on color 9 according to lighthouse

[silveltman]

I get a warning in lighthouse. I'm using tomato9 as button background, with white as text color.

The 9 step is only guaranteed to reach a 3:1 ratio for 600 weight font at 19px.

Since that's well documented I believe this is expected. You'll need to use a different step for that font size.
