I have 6 columns of numbers (search rankings) and I want to color cells in the second column that are less than the first in red and cells that are greater than in blue.

In the following columns I want to do the same thing except I want to compare the numbers in column 3 with column 2, 4 with 3, 5 with 4 and 6 with 5...

In addition it would be nice to bold or increase the font size on the cells that have a lesser or greater value of 10 or more in order to make them stand out.

Thanks!
