Yes, it works. In a Markdown cell, you just need to put the code in math mode and explicitly load the color module. Thus, this code

$$\require{color} \definecolor{energy}{RGB}{114,0,172} \definecolor{freq}{RGB}{45,177,93} \definecolor{spin}{RGB}{251,0,29} \definecolor{signal}{RGB}{18,110,213} \definecolor{circle}{RGB}{217,86,16} \definecolor{average}{RGB}{203,23,206} \color{energy} X_{\color{freq} k} \color{black} = \color{average} \frac{1}{N} \sum_{n=0}^{N-1} \color{signal}x_n \color{spin} e^{\mathrm{i} \color{circle} 2\pi \color{freq}k \color{average} \frac{n}{N}}$$

By the way, you have already asked about color in this other question. It seems that you haven't read the answers. It would be nice to mark some of them as accepted or comment why they are not valid.
