This is cool. I wonder... If you enter "first" (https://icotar.com/avatar/first) then enter in the primary color closest to the color of the background, a space, and the name of the picture, e.g. https://icotar.com/avatar/green%20snowflake and continue doing this, how far could it go before leading to a cycle, and what is the average distance to a cycle given some arbitrary input?
Sample: https://icotar.com/avatar/first https://icotar.com/avatar/green%20snowflake https://icotar.com/avatar/yellow%20plane https://icotar.com/avatar/blue%20car https://icotar.com/avatar/green%20waves https://icotar.com/avatar/green%20moon etc...
