Let’s take a look at an instance. Right here’s an e mail earlier than any filters have been utilized to it. 

It’s fairly easy, with black textual content on a white background. Now, let’s add a filter. 

That is how that very same e mail may seem to somebody with deuteranopia. Discover how the distinction between pink and inexperienced disappears virtually completely, and the e-mail seems to incorporate principally yellows and blues.

Now, right here’s our identical e mail as above, this time with the tritanopia filter utilized. Seems to be just a little totally different, proper? 

We will see three iterations of a message indicating a product’s inventory standing—however all three aren’t created equal. When the blues and yellows within the e mail are considerably decreased, the that means of every icon is clearest when the form of the icon communicates the standing of the product, not simply the coloration of the icon. 

This can be a nice instance of easy methods to use shapes to speak, relatively than—or along with—coloration.
