Some resources you might find useful for things like this:
- WebAIM: Contrast Checker (good for checking to see if text and background color choices are readable by most people; a 7:1 or higher contrast ratio is recommended)
- Coblis - Color Blindness Simulator (you can check screenshots to see how they’d look to different kinds of color blindnesses)
- How to Design for Color Blindness (a list of suggestions to increase accessibility for people with various visual impairments)
- PowerMapper’s SortSite - Accessibility Checker and Validator (online website accessibility checker)
Your dark green text on the blue background has a color contrast ratio of about 5:1, so you might want to change the text color to #76A77E to fix the contrast.
