bright-white style not working

The "bright-white" color does not seem to be working. both in the default theme or if i try to override. The resulting text is always black. Other colors seem to work without issue.

prettyError.appendStyle({
'pretty-error > header > title > kind':{
color: "bright-white"
}
}

Start by reproducing the bright-white color behavior in the default theme and with prettyError.appendStyle, comparing it with the other working colors. Trace the style handling for the "pretty-error > header > title > kind" selector. Done means bright-white renders correctly in both cases while existing colors continue to work.
