How do I interpret these transmission curves?

the wavelength is plotted in nanometers on the horizontal axis. 400nm corresponds to deep blue, 520nm to green and at 600nm to red
transmission, in %, is plotted on the vertical axis
visual filters: The gray curve shows the relative sensitivity of the dark adapted human eye at night
photographic filters: The gray curve shows the relative sensitivity of a typical CCD sensor
orange: the main emission lines which contribute to artificial sky glow, e.g lines from mercury (Hg) and sodium (Na)
green: the most important emission lines from nebulae, such as the lines from hydrogen (H-alpha and H-beta) and the lines from oxygen (OIII)
