To get the red color out of Red X it needs to be that vast majority of your grain bill and at the 1.050 gravity range. It gives a striking red color at that usage rate. At different amounts, or in combination with other malts, it will really only push you towards an orange hue. Flavor-wise I find it pretty close to a light Munich malt.
If you’re looking for a steeping grain to get a red color, a light touch of Roast Barley is probably the best option.
