Changing the "Almost Due" color in Email Advisor Desktop

In the Advisor Desktop on R21, the Due Date becomes a yellow/orange color when the SLA is almost up. I am working with a customer who believes that color is not easy to see. Can we change the default color for the “Almost Due” Due Date?

Thanks!

Please see below response from product expert:

Those colors are hardcoded and can’t be changed. The color settings comply with contrast settings under WCAG conformance standards (WCAG 2 Overview | Web Accessibility Initiative (WAI) | W3C) so it might be a monitor setting causing low contrast.
