A1. The correct answer is six. Sir Isaac Newton split sunlight through a prism and "invented" indigo [the "seventh" colour] because, as he was an alchemist, he believed in the supposed mystical power of seven, so added it to the colours he saw. As for schoolchildren learning the rhymn, with respect, it is an example of not believing everything taught in school.
A2. Water is blue. Although light reflected from the sky adds to the appearance, the colour blue can be seen under the surface.
A3. Although flamingos eat shrimps, their colour changes from grey of chicks to pink from eating blue/green algae, as found in African waters.
This week, for saying answer to Q3 that flamingoes are pink because "blood goes to their heads when the Queen of Hearts plays croquet with them, @pgn gets the award.
Thanks everyone for playing along and hope you will join in next week`s Thursday Challenge.
