I've been leaving reminders to myself with blue tape. 

If I see it on my Incra sled fine tuner that means it's not calibrated, because I used it . Same same with the TS-LS fence.

Blue tape over the blade slot on my TS means something, usually change the blade.

I need a different color tape to remind me about the blue tape. CRS has it's advantages, but not this time.
