"Colored lights may hypnotize..."
07 Sep '14 00:352 editsFrom a book; I will have to describe in words the diagram.
A board is divided into two rows of four cells. Starting upper left, we can label the first-row cells as 1, 2, 3, 4. We can label the cells in the row under them, from left, as 5, 6, 7, 8.
All of a sudden the board lights up the cells. Each cell is one of eight colors: red, yellow, orange, green, blue, indigo, violet, or tan. No color is repeated and all colors are used. Can you assign colors to cells, with the following clues?
i) One column has a red cell over a blue cell. Another column has an orange cell over a violet cell.
ii) Number 8 is tan.
iii) Green is to the right of orange, and violet is to the right of indigo.
iv) Blue is on an odd number, and indigo is on an even number.
v) Blue is to the left of indigo, and both orange and green are in cells with higher numbers than both red and yellow.
