Congratulations and Welcome!
The only place I've ever seen information on the valves is in the manual. Given the maze of hose behind the panel it would take a lot of time and patience to figure out each valve, but essentially they are changing the flow of water to perform the task they are set for. I don't think the colors mean anything, they just help make it easier to read the diagrams showing which way they need to be configured.
