We are attempting to create a design for an ad, either print or digital or both preferably, that appears differently when the person viewing the ad puts on a glasses with tinted lenses, like bright red or deep purple. So in the case of using red lenses, we are looking to have icons that clutter the design, with various shades of red, orange and yellow. We would like a message that is hard to decipher until the person viewing the ad puts on glasses with red lenses. Then most of the clutter disappears and the only thing that really appears is the message. Any advice or guidance would be greatly appreciated. Thanks.
When looking through red lenses, red in the image will be lightened; the complement of red, cyan, will be darkened. Thus, if the secret message is in relatively light cyan, patterns over it in red will obscure the cyan message normally, but the message will be more readable when wearing red lenses.
You can use a variety of colors with a high degree of R and a lower degree of B and G for the obscuring part of the image, and a variety of colors with low R and high B and G for the secret message.
