1 Common triggers of an anaphylactic reaction include drugs, such as penicillin, insect stings, foods (peanuts, shellfish), X-ray dye, and latex. 2  The symptoms of anaphylaxis may vary and can include hives, tongue swelling, vomiting, and even shock.  If someone is at risk, avoidance is the best form of treatment.
Ocean regions with high concentrations of phytoplankton will have shades of blue-green depending upon the type and density of the phytoplankton population there. The basic principle behind the remote sensing of ocean color from space is that the more phytoplankton is in the water, the greener it is.
Aquamarine Color. Like seawater, aquamarine can be light-blue, dark-blue, blue-green and green-blue. The more saturated the color, the higher the value, although almost all aquamarine is typically a lighter blue tone. A deeply saturated blue is the most desirable color, but it is very rare in larger specimens.
