if the tins are shown like this:

TIN A: 2:3

TIN B: 4:5

TIN A: can also be shown as 4:6

there for theirs is more blue in the first tin then second tin

The proportion of blue in Tin A is  3 / (3+2) = 3/5 = 0.6

In Tin B  proportion of blue = 5/ (5+4) = 5/9= 0.56

So Tin A has the greatest proportion of blue.
