This post is about complimentary colours and the name kind of gives it away… they complement each other! But which colours are complementary? Take a look at a colour wheel and draw a straight line from one edge, through the centre to the other edge and it’ll run through two colours. This pair sitting opposite each other on the wheel and are complementary.
So if you have a lovely orange-red yarn, what is opposite orange-red on the wheel? Green-blue.
The trick with using complementary colours is that just because they go together doesn’t mean you should do a 50/50 split between the two. In fact complementary colours work best if you use more of one and just a little of the other.
For example, if you’re designing stripes you might want to do thick stripes in one and thinner or fewer stripes in the other. But sometimes the yarn companies do the work for you, like where you have a yarn with a colour fleck in it, those are often complimentary to the base colour of the ply.
I like complimentary colours, because the right mixture of them always feels lively to me!
