Certainly, depending on what you're looking for. For a rich and luxurious purple, I would recommend using "wine" as a base with a touch of blue-violet added to it. This creates a deep, complex shade that can be both mysterious and elegant. As for reds, there are countless variations depending on the desired effect. A warm reddish orange could be created by mixing yellow and brown pigments together, while a cooler blue-based red could be achieved with a touch of cyan added to it.
