A few years ago I was thinking about colour and how strange it would be to be colour blind, or never see colour at all. Then I started thinking about how you would communicate colour to someone who had never seen it, you can’t say “it looks like what an orange tastes like”, that would make no sense. After I was done abusing my brain with those thoughts, I took it one step further and started wondering if everyone sees colour the same way. Take a strawberry for example, I see it as red, but you might see it as what I would call purple, but you would still call it red, because that’s how you see it, neither of us would be wrong because that’s how our brains interpret that colour. But, how would you be able tell if someone else sees colour differently than you? We both say the strawberry is red, and we just assume we see the colour the same way.
