Colors on are being updated to create more contrast between text and backgrounds as part of a continuous effort to make City services accessible to all. 

Old and New Breadcrumbs

Periodic accessibility tests and focus groups are done by the City of St. Louis web team to identify areas of that need improvement. The brighter blues, greens, and oranges of our previous design, when combined with white text, did not conform to the minimum contrast ratio of 4.5:1 set by Web Content Accessibility Guidelines (WCAG) 2.0. 

From the WCAG

The 4.5:1 ratio is used in this provision to account for the loss in contrast that results from moderately low visual acuity, congenital or acquired color deficiencies, or the loss of contrast sensitivity that typically accompanies aging.

These colors have been darkened and in some cases replaced to create a color scheme that is easier on the eyes, especially for folks who have low vision.
