In light mode especially, the type display that is tiny font of int, string, etc needs to be a darker shade than it currently is presenting since it is so small. To pass WCAG AA, it must be 4.5:1 ratio color. Even with changes in #297, the font does not pass. This color is set as an offset from the theme color for the actual data value that we set and provided to RJV. The only way we could make this color pass is to darken the overall color - but then it darkens/dulls out the overall presentation as the color is linked to the larger text. Some alerts may be for other parts of the RJV display because it is indicating manual check required due to opacity set by RJV on elements (the manual check for those is complete)
