Solder mask is a permanent protective coating on PCBs to prevent solder bridging, while solder paste is a temporary mixture of solder particles and flux applied to pads before component placement to facilitate soldering.
Green is the traditional color due to historical use of epoxy resins with bromine-based flame retardants, which produced a green hue; it also offers good contrast for inspection. Other colors are now available for branding or functional reasons.
Yes, minor damage can be repaired using epoxy-based solder mask inks or UV-curable patches, but extensive damage may require board rework or replacement to ensure reliability.
