How can I classify a type of action or content? Such as distinguishing two actions and content, the Customer and the Seller.
Would the use of colours be convenient? Example:
Blue buttons indicate actions a customer would take, blue icons (next to content) refers to content that will interest a customer.
Red buttons indicate actions a seller would take, red icons (next to content) refers to content that will interest a seller.
Are there better ways to do this? Such as only icons (inside buttons & next to content), which can be alot more memorable depending on the icon.
If using colors do they have to be opposites? For example this colour palette do not provides colours that are distinguishable such as blue and red and is one of the issues I am facing...
The users needs to distinguish the kind of content and action. On this platform the user is given the ability to buy and sell, such as in Ebay.
