Explaining a complex idea using only words is tricky. Even describing simple things exactly can be hard.

Try this:

Think of an inverted isosceles triangle that has an apex of 35 degrees. Colour it in with the colour that has the hex value #00a5ff. Here's a hint: that's a greenish blue.

Now, scroll down.


Keep going...


Is this what you have in your head?


Probably not exactly. Maybe not even close.

And I bet that if we compared notes, none of us would have come up with the exact same triangle.

But if, instead of describing the triangle to you, I had just shown it, how much simpler would that have been?
