If red is 1 and violet is 7 then, we will have
red= number 1
orange= 2
yellow= 3
green = 4
blue= 5
indigo= 6
violet= 7
now,
colour of the sky would be represented by number 5(blue) while colour of yolk will be represented by number 3(yellow). so, the statement is false.
KMNO4 has a violet colour which would be represented by the number 7 and danger or stop signal, whicj is red would be represented by number 1.
