Why does the color of my solution not look like that on your videos or sample photos?

The color of your solution will vary depending the on the age of the solution, the type of Ferric ammonium citrate used (Brown or green) the mixing ration used, conditions under which the paper dried and type of paper used. This does not indicate a faulty mixture, variations in color from Bright orange/ yellow for the use of brown ferric ammonium citrate to light yellow – green for the use of green ferric ammonium citrate is completely normal. I have also had pages that has been dried for several weeks that have turned a dark green/blue that has still produced stunning prints.
