So you have bought a lovely blue yarn and you think how great it will look with that other blue yarn in your stash, but when you put them side by side you realise they don’t look good together. Why? A common reason is that one is a warm blue and the other a cool blue.
What does that mean? Well, when colours have more red or yellow in them they tend to be warm and when they have more blue or green in them they tend to be cool. Usually what you’ll notice is that one seems livelier (warm) and one seems duller (cool). The tricky thing is that it can be hard to see until you compare them.
If you don’t feel that you really get this idea, take a trip to your local hardware store or paint store – anywhere that has one of those collections of colour cards/paint chips. Pick a couple of different greys and put them next to each other and do the same for whites. You should be able to see what’s warm and what’s cool easily with whites and greys.
Then grab different yellows, reds, blues and greens and compare. You should see what’s lively/dull or more pink/more blue (more yellow/more green)!
But what happens if you mix warm and cool colours? Usually you end up with a slightly “flat” result where the colours look dull, but you can get “muddy” colours that take on a brown or grey appearance too.
If you’re not sure about a combo of yarns… sample!
