It's somewhat common, though not at all remarkable, that we're often asked to 'please fix the colour' within a piece of design collateral. The question is nearly always asked as though the colour needing to be 'fixed' is a given. No other possibilities considered - and why would there be? The colour doesn't look correct, so fix it.
Right?
Well, as you'll see from the image here, sometimes the colour is just fine and dandy. It's you, the beholder, who needs fixing. Or more correctly, your eyes and brain need to evolve just a little more to overcome the problem of 'bridging information gaps' which result in an incorrect analysis.
So, you're looking at embedded spirals, of green, pinkish-orange, and blue. Right?
Wrong! What you think is blue is precisely the same colour as the green. Go ahead - grab the image and blow it up. It's green I say. Green green green.
The reason they look different colours is purely because our brain judges the colour of an object by comparing it to surrounding colours. In this case, the stripes are not continuous as they appear at first glance. The orange stripes don’t go through the 'blue' spiral, and the magenta ones don’t go through the 'green' one.
Without us being consciously aware of it, our brains compare that spiral to the orange stripes, forcing it to think the spiral is green. The magenta stripes make the other part of the spiral look blue, even though they are exactly the same colour. The overall pattern is a spiral shape because our brain likes to fill in missing bits to a pattern. Even though the stripes are not the same color all the way around the spiral, the overlapping spirals makes our brain think they are. The very fact that you have to examine the picture closely to figure out any of this at all shows just how easily our little brains can be tricked. Grrrr!!
Anyway, just spare a thought about this the next time you think your Pantone 405 doesn't look quite right. Perhaps the reality is actually different to what you're seeing.
