Don't spray paint your containers - just keep them in a darkish place. The inside of a closed cupboard or a Rubbermaid tote will do fine.

In most cases, you don't even have to do that, as most of the chemistry isn't sensitive to normal light levels.

Clear containers permit you to monitor the contents without opening them.
