A very easy and efficient reality check.

If you have one of those digital watches that beep every hour, every time it does take a look at your hands. Question the reality and make sure you have five fingers and that they look okay. Check twice on this. You will get used to do that and you will find yourself doing it in a dream but finding an abnormal hand and turning lucid.

If you do not have said watch, then just try to find another trigger, such as a color as you said or something else, but pink is an uncommon color, try to do with green for an instance. You might see a lot of green, well, better, that way you RC more.

Good luck!
