How can I get a list of dark color codes in HTML format?

Question

Working with color

Hello, I need to make a
background / text color generator so that the color does not match the background. Background
colors are stored in one file, text colors in another and I need an arbitrary background color string to be combined with an arbitrary text color string (that is, it was readable)
how colors are generated #000000 - #FFFFFF ? How to get a complete list of dark colors and a list of light ones?

It looks like you have to manually compose "readable" background-text pairs.
