Most terminal color palettes have colorschemes that are customizable. Many terminal users make use of some standard colorscheme such as solarized.
I'm building a terminal application that needs to use colors. My question is, how do I know which color combinations from the terminal color palette go well together? For instance, in the colorschemes that I use, the last color in the palette generally serves well as an alternative background color, but I couldn't afford the risk that some text is hardly visible for someone else because of his different colorscheme.
Are there any conventions on this?
