This week's Blackbox is not designed to add an effect, border, or odd distortion (although you can certainly use it as an effect if you want to!). Instead, it's meant to be used as a tool to show your images as someone with color blindness would see them. This simple filter will convert the colors in any image to show the four major types of color blindness (Trianopia, Protanopia, Deuteranopia, & Monochromacy). It's a great way to test how your image, web page, or graphics will look for these viewers - and especially helpful if you want to make your creation or website 100% user friendly.
Just search for "color blindness" in the Blackbox browser (Go to File -> Import Blackbox) and you'll have a secret weapon for knowing how everyone will see your creations!
