Is it Blue or is it White?

Last night I’m browsing around my favorite social media sites, and I’m flooded with images of THE dress which is clearly white and gold (and clearly over exploited). Even though everyone says it is blue and black. How do you get blue and black confused with white and gold? Turns out that science is involved. People much smarter than me have pointed out that this is simple optical illusion (see the photo below). I don’t think the people taking the picture meant to trick everyone, but I wouldn’t be surprised, if they did.

Here is another example

Color Letter
The blocks containing “A” and “B” are the same color

This optical illusion had me very concerned. Two of our product lines use a white label or a blue label to differentiate between products.

Take for instance the High Powered Cold Gun and the Standard Cold Gun. The labels are the similar, but one is white and one is blue.

Standard Cold Gun (Left) has a white label High Powered Cold Gun (right) blue label.

The Standard Cold Gun will generate 1,000 BTU/HR of cooling, and The High Powered Cold Gun can generate up to 2,000 BTU/HR. of cooling. I would hate for someone to confuse the two units.

Or look at the Reversible Drum Vac versus the High Lift Reversible Drum Vac?

The High Lift Reversible Drum Vac will lift liquids up to 15 feet vertically. The Reversible Drum Vac can pump 55 gallons in 90 seconds but is limited to 9′ vertical lift.

Could these products be confused, if someone takes a photo with lighting from the back? Sure, they could given the correct conditions, but the labels also say the “High Power” or “High Lift”. I think we can still tell the difference between the products. Man, that’s a relief. Here is a link to another photo of the dress. I was tricked, clearly it is black and blue.
