Contrastinformationisalsoprovided-youcanseehowreadabletextisbasedoncontrastbetweentextcolorandbackground,iconsundercolorpickersrepresentcontrastratingbasedon[WCAG](https://www.w3.org/TR/2008/REC-WCAG20-20081211/#visual-audio-contrast-contrast) - thumbs up means AAA rating (good), half-filled circle means AA rating (acceptable) and warning icon means it doesn't pass the minimal contrast requirement and probably will be less readable, especially for vision-challenged people, you can hover over icon to see more detailed information. *Please note* that if background is not opaque (opacity != 1) contrast will be measured based on "worst case scenario", i.e. behind semi-transparent background lies some solid color that makes text harder to read, this however is still inaccurate because it doesn't account that background can be noisy/busy, making text even harder to read.
