Interactive Element Affordance
Interactive Element AffordanceInteractive element affordance means that clickable things should look clickable. A button should look like a button. A link should look like a link. When interactive elements blend in with static content, users do not know they can interact with them — and they will not. Good affordance uses visual cues like color, shape, underlines, cursor changes, and hover effects to make it obvious what can be clicked, tapped, or activated. Why It Matters

What Does "Liquid Purple" mean?
noun | / LIK-wid PUR-pul /
- (biochemistry) Also known as visual purple or rhodopsin — a light-sensitive receptor protein found in the rods of the retina. It enables vision in dim light by transforming invisible darkness into visible form. Derived from the Greek rhódon (rose) and ópsis (sight), its name reflects its delicate pink hue and vital role in perception.
- (modern usage) Liquid Purple — a digital marketing agency specializing in uncovering unseen opportunities and illuminating brands hidden in the digital dark. Much like its biological namesake, Liquid Purple transforms faint signals into clear visibility — revealing what others overlook and bringing businesses into the light.
Origin: From the scientific term rhodopsin, discovered by Franz Christian Boll in 1876; adopted metaphorically by a marketing firm dedicated to visual clarity in the age of algorithms.
