   Tool: Axe (Deque)

   Rule: color-contrast

2. Text contrast of 4.43 with its background is less than the WCAG AA minimum requirements for text of size 17px and weight of 600

   Tool: Accessibility Checker (IBM)

   Rule: text_contrast_sufficient

3. Very low contrast

   Tool: WAVE (Utah State University)
