Add a "warning" color
ValidatedField
display a warning, as distinct from an error:
There's no color in VARIABLES.md
for this, so @g-sam added one in pubsweet@c2a1d54b. We shouldn't have discrepancies between the official variables and what's in the default theme, so we should either remove the warning function or add colorWarning
to VARIABLES.md
.
Thoughts?
