dark urine
orange!
The blue colored glucose indicator is something called "Benedict". Glucose has no color to start off with. Once you add benedict to it inside a testube, you have to heat it up in a waterbath. The color you should get it a green, yellow, orange (you should get this color mostly), orange-red, or brick red depending on how much glucose is in the solution.
Glucose is high in the urine of an untreated diabetic. Glucose itself makes the urine hyperosmolar (concentrated with solutes), which in turn makes it absorb extra water from surrounding tissues, which creates extra, dilute urine. This in turn dehydrates the surrounding tissues making the patient thirsty.

Depending on the amount of glucose (sugar) that is present, the solution will turn a certain color. The progression goes as follows: blue (no glucose present), green, yellow, orange, red, and then brick red or brown for a very high glucose content.
In some pools, the cleaners add a chemical into the water, to turn urine blue. Most pools don't have these on these days. But in a pool without the chemical, no urine doesn't change color.
When your urine is a darker color, that means you are dehydrated.
Normal urine color results from a pigment called urochrome. The actual tint will depend on the concentration or dilution of the urine. The color of urine may not always be normal; B vitamins, for example, turn urine green, and carrot juice can turn it orange.UrochromeUrochrome Urochrome
If your urine is any color but yellow i would suggest consulting your family physician. However, having clear urine is completely normal and is actually the most healthy color urine to have. There is really not a vitamin to turn your urine a specific color.
It appears if turn your urine red/pinkish and smell like vitamin B.
