For instance, red is high temp, blue is muti purpose, clear is an adhesive, black is oil resistant etc. Hardware store silicones are colored for asthetic purposes, As a rule clear is usually the only pure silicone, and many of the clear silicones have anti-mildew additives as mentioned. I recently bought a new tank that had a transparent black (more of a charcoal grey) silicone on it so someone is making a black aquarium silicone now. Since the clear is the best adhesive as a rule and also the purest, It would be my reccomendation, if you do chose a colored silicone, read the label carefully if it doesn't list aquariums under uses, don't use it. the additives will cause much gnashing of teeth later on.
