1.3.3 Sensory characteristics
The guideline says: Instructions provided for understanding and operating content do not rely solely on sensory characteristics of components such as shape, colour, size, visual location, orientation, or sound. What does that mean? We come back to colour in more detail in a later guideline but this one is really very general. It refers to any item on the page that isn't text or a described image... things like navigation buttons, ways of categorising, making choices... anything where the user has to choose based on a colour, a shape, where something is on the page... that kind of thing. What do I need to do? This could be misinterpreted as an instruction to avoid the use of colour, shape, position and so on... but all it really is, is a reminder that you need more. You can have an arrow at the bottom of the page for your next button, but just make sure it is labelled in such a way that a screen reader can read it. It may need alt text, for example. I think one of the worst offender...
