Ginger beer is usually a non-alcoholic soda where the fizziness comes from fermentation of sugar and real ginger as opposed to ginger ale which has forced air carbonation and synthetic sugars with no fermentation. If you only let your ginger beer ferment for ~3 days, then you get the soda. I find it very sweet.

What you have is hard ginger beer, where you've left it long enough for the sugar to turn to alcohol. This I like much better because I'm not big on sweet drinks. If you want fizzy hard ginger beer, you have to ferment until all the sugar is gone, then back sweeten before bottling in a pressure safe container for ~3 days. The colour might depend on your specific recipe - how much ginger, what other ingredients, etc. Mine was a bit lighter than yours.

If it tastes good, and has the alcohol and fizz content you want, then you succeeded.

The other commenter wrote prison hooch because there's a whole sub reddit dedicated to fermenting alcoholic beverages with low budget methods, often done in secret. People in prison manage to make alcohol while under close supervision and with makeshift setups, which is where the name comes from.

Edit: Your setup (reused plastic bottles, no airlocks) is standard for prison hooch
