Hello, According to Newton's studies, the tradition in France says that a rainbow is made of 7 colours : Fr. Violet, indigo, bleu, vert, jaune, orange, rouge (Eng. violet, indigo, blue, green, yellow, orange, red) Actually, the number of colours is infinite... My question : how many colours do you traditionnally see in a rainbow according to your language/culture ? I would like to know if the lack of a colour word (e.g. orange) could lead to rainbows with less colours or if your language possesses other specific colours that we could find in a rainbow with 8 or 9 or more colours.
