Multicolored Keyless Entry System
mollyhackit writes "Here's a how-to guide for building a keyless entry that uses color identification instead of numbers. All eight buttons are initially blue; as you press the individual buttons they change color. Cycle the colors to your particular pattern, and you're in. This lock obviously wasn't designed for high security use since anyone in the same room would be able to see you and your amazing technicolor dream lock's pattern; it's just a fun project and will keep the youngins out of your workshop (timer prevents brute forcing). The RGB buttons are monome clones from hobby shop Sparkfun."
Only if the value is different can a color-blind person tell that the colors are different. If you tell them that the red is darker than the green, they can then tell you which one is darker than the other if they're next to each other, but if all they have is blue, brown, and yellow to choose from, they have no idea if that brown is the red or the green.

I'm colorblind.
Red-green, but not too badly. I get along just fine, but fuck those test patterns. There was some kind of a jumbo poster ad with that pattern, and the only time I was able to read it was at night, from a sufficient distance.
Certain shades of red, green, purple, brown and grey simply blend into each other. When I see something colored like that, I can't even name the color.
Kind of like someone tone-deaf guessing whether he heard a C or an E note. He can hear whether it was high or low, just like I see whether it is light or dark, but other than that, I simply cannot name it.
For instance, most of this /. page is green. Though it may be light brown.
The frame around the text field I'm typing my answer in is a different shade of green, but it might also be grey.
I'm leaning towards green, but I don't really see it.
Ignore this signature. By order.
