Company colors don’t pass contrast guidelines.
Question
Answer
Company logos do not need to meet accessibility criterion per WCAG 1.4.3 ("Text that is part of a logo or brand name has no contrast requirement"). However, if you have flexibility with the logo design and can make it pass contrast guidelines, that's a great thing to do.
All other text must meet the minimum contrast ratios. Therefore, you'll need to adjust the colors used for text and backgrounds to comply with these standards. For AA compliance, normal text must have a contrast ratio of at least 4.5:1, and large text must have a ratio of 3:1 against the background. For AAA compliance, the requirements are a 7:1 ratio for normal text and 4.5:1 for large text. Additionally, AA compliance requires that visual information used to identify UI components (such as controls) must have a 3:1 contrast ratio against adjacent colors.
