Stroop!

I can't write in colour here
But you'll know what I mean
When I write the word 'blue'
But the font is in green

The name of the game:
Say the font colour, not word
For some people it's easy
But for others absurd

This is the 'Stroop Test'
A psychologist from the past
To test if our reflexes
Are quite slow or fast

It's harder than you think
Stroop was a clever fellow
Just try saying 'purple'
When the written word is yellow!

The point of this is
We're easily confused
We process words faster
Than we do hue

I know it's only trivia
But it fascinates me
So I'm sharing it here
For you all to see.
