Why is your urine clear after you drink large amounts of alcohol if it actually dehydrates you, when the color of your urine is an indication of hydration?

When you are well hydrated, your body expels the excess water, which dilutes your urine so that it becomes clearer. It eventually stops this when your hydration levels are within the regulated limits. The colour of your urine in an indication of hydration only under normal conditions.

When you drink alcohol, it causes your kidneys to expel more water regardless of how well hydrated you may or may not be. As a result, your urine becomes more clear as it becomes diluted. However, you will continue expelling excess water in your urine until the effects of the alcohol wear off.
