Which color is not used as a sea name?

Blue. Both squids and oc­to­pus­es have blue blood. They use an oxy­gen-­car­ry­ing molecule in their blood called hemo­cyanin that contains copper. In cold con­di­tions with low oxygen pres­sure, hemo­cyanin oxygen trans­porta­tion is more ef­fi­cient than he­mo­glo­bin oxygen trans­porta­tion.

It is gypsum. White Sands, having 442 total square kilo­me­ters of dune fields, is the world's largest surface deposit of gypsum. Unlike other desert sands, it is cool to the touch, due to the high rate of evap­o­ra­tion of surface moisture and the fact that the sands reflect, rather than absorb, the sun's rays.

Men. It is much less likely for a woman to be red-­green col­or­blind than a man, since this common type of color blind­ness is caused by a re­ces­sive gene in the X chro­mo­some. For a woman, both of her X chro­mo­somes would have to be af­fect­ed. A man only has one X chro­mo­some, so he is more likely to be col­or-blind.

It is obtained from oils and fats. Soaps for cleans­ing are obtained by treating veg­etable or animal oils and fats with a strongly alkaline so­lu­tion. This chemical reaction is known as saponi­fi­ca­tion.
