# PROMPT COLOR INFO
# BACKGROUND                            COLOR (LEFT VALUE)              TYPE (RIGHT VALUE)
# Black background: 40                  Black: 30                       Normal Text: 0
# Blue background: 44                   Blue: 34                        Bold or Light Text: 1 (It depends on the terminal emulator.)
# Cyan background: 46                   Cyan: 36                        Dim Text: 2
# Green background: 42                  Green: 32                       Underlined Text: 4
# Purple background: 45                 Purple: 35                      Blinking Text: 5 (This does not work in most terminal emulators.)
# Red background: 41                    Red: 31                         Reversed Text: 7 (This inverts the foreground and background colors, so you’ll see black text on a white background if the current text is white text on a black background.)
# White background: 47                  White: 37                       Hidden Text: 8
# Yellow background: 43                 Yellow: 33
