Well if they shouldn’t be, then someone better tell Mother Nature!
Despite the old saying – “blue and green should be never seen without a colour in between” – the truth is, these two colours are great together.
And thankfully now days more & more patterned paper is doing this combination. Take CTMH Skylark paper pack with the lovely pale blues & greens, while it does include a Kraft Brown in there.
I think with any colour combination you are always going to find an example where it doesn’t work – it is more about the tone of the colour then the actual combination itself. I also think the trick is to ensure that one colour does not overwhelm the other & ensure that they are all of the same intensity and undertone.
Have fun working with your Skylark paper pack & working with Blue & Green.
