Accessibility
It's important to choose a color with a contrast ratio that meets accessibility standards. This helps to improve readability for users with sight impairment or color blindness. Accessibility guidelines recommend a color contrast ratio of at least 4.5:1 when the color is compared against white.
To test whether the color you want to use meets this requirement, you can use an online tool from WebAIM: https://webaim.org/resources/contrastchecker/
Paste the hex code for your chosen color in the Foreground Hex Value field. Leave the Background Hex Value field set at #FFFFFF (white). The tool provides a contrast ratio, and tells you whether the ratio meets applicable standards.
