A mnemonic to remember the colors and their meaning is:
 
: White over White, you're high as a kite / you'll fly all night / check your height / you're out of sight / too much height.
: Red over White, you're alright / height's alright.
: Red over Red, you're dead / pilot's dead.<ref>[https://www.skybrary.aero/index.php/Visual_Approach_Slope_Indicator_Systems_(VASIS) Skybrary]</ref>
 
(White over Red is not possible.)
