Specify colors for the menu. normal represents the color used for normal menu text, while highlight represents the color used to highlight the line the cursor is on. Both normal and highlight are specified as two symbolic color names, for foreground and background color, separated by a slash. For example:
color light-gray/blue cyan/black
You can prefix the foreground color with blink- (e.g., blink-cyan/red) to get a blinking foreground. The colors black, blue, green, cyan, red, magenta, brown, and light-gray can be specified for foreground or background. Additional colors that can be used only for the foreground are dark-gray, light-blue, light-green, light-cyan, light-red, light-magenta, yellow, and white.
