Pine Script Indicator

Hi, I am looking to have an indicator created in pine script. (hopefully fairly simple). I use the standard RSI script twice. I change the RSI on each to whatever I want, as well as different colors. I unselect the RSI-based MA on both. I then pin them both to scale Z. After that, what I am looking for is for the indicator to color code the candles on the chart based on which line is above or below the other.
