Chroma-Hash displays an ambient color representation of the input as
it is being typed.
Use Case 1: Login Check
If your password normally is represented as red, purple, orange,
and after youve finished typing you see pink, green, grey, youll
know you mistyped it somewhere along the way. This avoids a
potentially long wait for the server to respond with a failed login
Use Case 2: Password Confirmation
When you sign up for a web service, you often have to type your
password twice to make sure that you entered what you wanted
correctly. As in the demo, a user will be able to confirm that two
fields are the same visually. There are, of course, many alternatives
for live-input validation of password confirmation, but this is
another viable use case for Chroma-Hash.
