Red only works if you have color vision. It shouldn't be relied on. (Traffic lights, for example, have a consistent order with red on top.)

- mattowen_uk 6y agoUnless they are the ones used on the railways, where the red light is on the bottom. Reason for this apparently, means that a build up of snow can't obscure it, causing a driver to not see it and ram up the back of another train. Of course nowadays, there's overrides to stop trains running red lights, but the red lights are still orientated at the bottom.
- eru 6y agoIt's still consistent. It's just not the same pattern for roads and railways, but that's fine.
- Rebelgecko 6y agoWith the most common forms of color blindness (and maybe all of them?), people can still tell the difference between a white button and a red one
- rightbyte 6y agoConcerning traffic lights color blind can see which one is lit, too. UI buttons doesn't have that feedback mostly (unless greyed out as inactive etc).
