Having a look on the mydsl repositories. What does the 'Lv' column and coloured squares represent?

ke4nt1: The repository will soon be upgraded to a more automated method of display, which will self-check extensions for possible conflicts and risk. and rate them according to a "color" scheme.
Over the past couple of weeks I have been working with ke4nt1 to improve the repository. The color coding is the last part of the planned improvements. I know a legend is needed. It will be comming soon. The colors are to help the user know more about the extension's requirements or possible impacts to the base system. So the Lv column is the Level with blue, green, yellow, and red in order of least to most "risk" or impact of system resources.The new pages are now live.
