Draea, I've worked with all sorts of grouts and colors. A pro tile person wouldn't 'improperly' mix it. you add water and mix it like cake batter. If you don't use enough water, it's too dry. if you use too much water, it's too runny. ( but it's still going to be the same color. ) After mixing, you let it slake for 10 mins. then you grout. Even if you only let it sit for 2 mins, it's still not going to change colors. There's no way to get it to change color unless you use muddy water. And even then, it wouldn't be consistent. you'd have light and dark spots. no. it's the wrong color.
