Clarify the purpose of the parameter by renaming it to the "background" that is a boolean. Also, change the .value field in the color struct from storing 0-7 for basic 8 colors to storing 30-37 for ANSI colors. This aligns the code to show ANSI colors to the code for the 256 color scheme, which already uses the actual value to be sent to the terminal.
