Pattern Colour Variations

Something I got feedback on from the crit was the colours I was using in 
my designs.
I had only just started to apply colour so before I go to print I am trying 
out different colour combinations with different patterns on the different
stationary items.

With these designs I have looked at background colour for the rulers,
leaving the patterns black and white. I have tried it with a range of
patterns that work with the ruler dimensions.

Another variation I have looked at is changing the colour of the pattern
itself, I have used the same colour palate in all the designs just changing
the combinations and where the colours are used.
I am going to print these to see which ones work best in print and with 
the ruler.
