What Colour is the Benedict's solution?

Keeping this in consideration, what is the original Colour of Benedict's solution?
The formation of the insoluble type of red precipitate takes place. The color of the precipitates is considered as the result of the Benedict's test. The original color of the benedict's solution is turquoise or deep blue. The Benedict's solution is known as the alkaline solution.
Also, why does Benedict's solution change Colour? When Benedict's solution and simple carbohydrates are heated, the solution changes to orange red/ brick red. This reaction is caused by the reducing property of simple carbohydrates. The copper (II) ions in the Benedict's solution are reduced to Copper (I) ions, which causes the color change.
Just so, what color is a positive Benedict's test?
A positive test with Benedict's reagent is shown by a color change from clear blue to a brick-red precipitate. Generally, Benedict's test detects the presence of aldehydes and alpha-hydroxy-ketones, also by hemiacetal, including those that occur in certain ketoses.
How do you make Benedict's solution?
One litre of Benedict's reagent can be prepared by mixing 17.3 grams of copper sulfate pentahydrate (CuSO4. 5H2O), 100 grams of sodium carbonate (Na2CO3), and 173 grams of sodium citrate in distilled water (required quantity).
