You get blue-green.

The blue color of glass-lined reactor coatings is due to the presence of cobalt oxide in the enamel formulation. Cobalt oxide is added to the enamel to enhance corrosion resistance and create a durable and chemically resistant coating. The blue color is also a visual indicator that the glass lining is intact and the reactor is properly protected against chemical reactions.
Glass lined reactors are often coated with a blue-violet enamel to protect the inner glass surface from corrosion and chemical reactions. This coating helps to extend the lifespan of the reactor and ensures the purity of the substances being processed inside it. The violet color is a result of the specific type of enamel used in the coating process.
Glass lined reactors are typically coated with a blue enamel, which is a type of protective coating. The blue color is not necessarily a standard requirement, but it is commonly used for easy identification and to differentiate it from other types of reactors. The blue enamel helps to provide resistance against corrosion and high temperatures, making it a suitable choice for chemical processing applications.

I think "Blue" not sure though
Blue-lined Sabertooth Blenny was created in 1852.
Sea is actually not blue its transprent.If you take some water in a transprent glass its transprent.there actually a blue pigment present in there.The blue you see (haha) is the color of the reflected sky above itsunlight have 7 colour .when the sunlight enter in water some of colour will reflaction from water but blue colour is not reflactiol all some of colour will be left in water sothat seawater looking blue.
