Does Schwarzkopf 'Smouldering Red' (L43) take well to unnaturally black hair?

The last time I dyed my hair was about two months ago. So right now it's a dark brown/black. Today I bought Schwarzkopf's Brilliance Luminance 'Smouldering Red' and I was wondering if anyone knew how well it might turn out? I'm a little skeptical, but I have my fingers crossed. I have another black dye on me in case things don't work out too well.
